What is a rectangle class 6?
A rectangle is a four-sided polygon in which the opposite sides are parallel and equal to each other. It is one of the types of quadrilaterals in which all four angles are right angles or equal to 90 degrees. The rectangle is a special type of parallelogram with all its angles equal.
A rectangle is a 2D shape that has 4 sides, 4 corners, and 4 right angles. Opposite sides of a rectangle shape are the same length, with one pair being longer than the other pair. If all the sides of a rectangle were the same size, it would be known as a square.
Area is defined as the total space taken up by a flat (2-D) surface or shape of an object. Take a pencil and draw a square on a piece of paper. It is a 2-D figure. The space the shape takes up on the paper is called its Area.
A rectangle is a closed 2-D shape, having 4 sides, 4 corners, and 4 right angles (90°). The opposite sides of a rectangle are equal and parallel. Since, a rectangle is a 2-D shape, it is characterized by two dimensions, length, and width. Length is the longer side of the rectangle and width is the shorter side.
Definition. Square is a regular quadrilateral, which has all the four sides of equal length and all four angles are also equal. The angles of the square are at right-angle or equal to 90-degrees. Also, the diagonals of the square are equal and bisect each other at 90 degrees.
: a four-sided polygon that has four right angles and each pair of opposite sides parallel and of the same length.
a flat shape with four sides and four 90° angles, with opposite sides of equal length and two sides longer than the other two.
In geometry, the perimeter of a shape is defined as the total length of its boundary. The perimeter of a shape is determined by adding the length of all the sides and edges enclosing the shape.
The area is the region covered by shape or figure whereas perimeter is the distance covered by outer boundary of the shape. The unit of area is given by square unit or unit2 and unit of perimeter is same as the unit.
Volume is a three-dimensional quantity that is used to measure the capacity of a solid shape. It means the amount of three-dimensional space a closed figure can occupy is measured by its volume.
What is length class 5?
Length is the longest extent of anything. Mass is the measure of amount of matter.
Perimeter of Rectangle = 2 (Length + Width).

- square.
- All the angles of a rectangle are 90°
- Opposite sides of a rectangle are equal and Parallel.
- Diagonals of a rectangle bisect each other.
A square is a quadrilateral with four sides and four vertices. All four sides of a square are equal in length. The opposite sides of a square are parallel to each other. All the diagonals of a square have the same length.
A square is a two-dimensional closed shape with 4 equal sides and 4 vertices. Its opposite sides are parallel to each other. We can also think of a square as a rectangle with equal length and breadth.
Square Numbers: Multiplying With The Same Number
For example, 3 multiplied by 3 is equal to 3-squared or 3 x 3 = 32. So, basically, the exponential form of multiplication of a number or integer by itself is called a square number.
- A rectangle is a quadrilateral with four equal interior angles.
- The opposite sides of a rectangle are equal and parallel to each other.
- The interior angle of a rectangle at each vertex measures 90°.
- The sum of all the interior angles of a rectangle is 360°.
In geometry, something that is rectangular had four sides and four right angles. Cereal boxes, dollar bills, and many cell phones have a rectangular shape. Anything shaped like a rectangle is rectangular.

What is a rectangle shape called?
In Euclidean plane geometry, a rectangle is a quadrilateral with four right angles. It can also be defined as: an equiangular quadrilateral, since equiangular means that all of its angles are equal (360°/4 = 90°); or a parallelogram containing a right angle.
A rectangle is a quadrilateral, all of whose angles are equal i.e. right angles. Square, apart from all equal angles, also has all sides equal. Hence, square is a special case of rectangle. In other words rectangle is sometimes a square (when all sides too are equal).
- Draw a straight, horizontal line using a ruler. ...
- Make a shorter vertical line coming down from one end of the first line. ...
- Draw a horizontal line coming off the bottom end of the vertical line. ...
- Draw a vertical line between the ends of the two horizontal lines. ...
- Color in your rectangle to make it pop.
The rect in rectangle comes from the Latin rectus, which means "right" or "straight." Because of its right angles, a rectangle has straight sides. Another word with the same root is rectitude, which means moral uprightness.
Thus every square is a rectangle because it is a quadrilateral with all four angles right angles. However not every rectangle is a square, to be a square its sides must have the same length.
The reason most commercial designs are rectangular, or square, is because they are easier, faster and more economical to build out of ordinary materials – stone, concrete, brick or wood. Square and rectangular shapes are also exponentially easier to reconcile, and there's usually less waste.
We know that, perimeter of a rectangle = 2 (Length + Breadth) units.
Perimeter is the sum of all the sides of a polygon, such as: Perimeter of square = Sum of all four sides. Perimeter of rectangle = Sum of all four sides. Perimeter of triangle = Sum of all three sides.
In Maths or in Geometry, a Cube is a solid three-dimensional figure, which has 6 square faces, 8 vertices and 12 edges.
It is amount of space occupied by a three-dimensional object or region of space. Volumesare expressed in cubic units.
What is length measurement class 6?
Length, in general, is the measurement of distance. The SI unit of length is a metre (m). One metre (m) is divided into 100 equal parts called centimetre (cm). One centimetre (cm) has 10 equal parts called millimetre (mm).
| 10 millimeters (mm) | 1 centimeter (cm) |
|---|---|
| 100 centimeters | 1 meter (m) |
| 100 meters | 1 kilometer (km) |
| 1 Ft | 12 Inch |
| 1 Mile | 5280 Foot |
Measurement is a comparison of an unknown quantity with a known fixed quantity of the same kind. The value obtained on measuring a quantity is called its magnitude. Magnitude of a quantity is expressed as numbers in its units.
The class width is the difference between the lower limits of two consecutive classes or the upper limits of two consecutive classes. If 5-10 is one class, the next class should be 10-15. Class width is 10-5=5.
Mean is the average of the given numbers and is calculated by dividing the sum of given numbers by the total number of numbers.
To find the area of a rectangle, we multiply the length of the rectangle by the width of the rectangle.
Rectangle Formulas. Perimeter of a Rectangle Formula. P = 2 (l + b) Area of a Rectangle Formula. A = l × b.
What is the Formula for the Area of a Rectangle? The area of a rectangle (A) is the product of its length 'a' and width or breadth 'b'. So, Area of Rectangle = (a × b) square units.
- parallelogram.
- quadrilateral.
- rectangle.
- rhombus.
- square.
Answer and Explanation: Some other names that we use for rectangles are parallelograms, quadrilaterals, and polygons. This is because the definition of a rectangle demonstrates that it satisfies the definitions of each of these other shapes.
What is a rectangle class 8?
A rectangle is a quadrilateral with four right angles. Thus, all the angles in a rectangle are equal (360°/4 = 90°). Moreover, the opposite sides of a rectangle are parallel and equal, and diagonals bisect each other.
A rectangle has four sides with the opposite sides equal to each other and with the adjacent sides meeting at 90°. These properties are seen in the two types of rectangles - the Square and the Golden Rectangle.
A cuboid is like the 3D version of a rectangle.
Thus every square is a rectangle because it is a quadrilateral with all four angles right angles. However not every rectangle is a square, to be a square its sides must have the same length.
- boxlike.
- boxy.
- equal-sided.
- equilateral.

To show that ABCD is a rectangle, we have to prove that one of its interior angles is 90°. Hence, ∠B = ∠D = ∠C = ∠A = 90° [Since opposite angles of a parallelogram are equal]. Since ABCD is a parallelogram and one of its interior angles is 90°, ABCD is a rectangle.
A cuboid is a three dimensional solid that has 6 faces (rectangular), 8 vertices and 12 edges. A cuboid has three dimensions such as length, width and height. A perfect cuboid is said to be a cuboid that has integer edges.
A rhombus is a special case of a parallelogram. In a rhombus, opposite sides are parallel and the opposite angles are equal. Moreover, all the sides of a rhombus are equal in length, and the diagonals bisect each other at right angles.
