What is Rectangle?

A rectangle is a 2D shape in geometry, having 4 sides and also 4 corners. Its 2 sides accomplish at best angles. Thus, a rectangle has actually 4 angles, every measuring 90 ̊. The opposite sides of a rectangle have the very same lengths and also are parallel. Two sides are said to it is in parallel, when the distance in between them remains the very same at all points.

Properties of a rectangle:

It is a level shape

It has actually 4 political parties (edges)

It has 4 corners (vertices)

It has actually 4 right angles

Area of a rectangle:

The area that a rectangle is the product the its two surrounding sides

*

Area that a rectangle = length × Width

Perimeter:

The perimeter that a rectangle is the sum of the length of its four sides. Since parallel sides of a rectangle have the same length, the formula because that the perimeter of a rectangle is

Perimeter of a rectangle = size + broad +Length + Width

=2 size +2Width

=2 (length +Width)

Diagonals the a rectangle:

The line segments that join the the opposite corners the a rectangle are referred to as its diagonals. In the offered figure, the 2 diagonals the the rectangle room AC and BD. The diagonals that a rectangle room the very same in length.
