Introduction to rectangle

A rectangle is a 4-sided flat shape with straight sides where all interior angles are right angles (90°).

Also opposite sides are parallel and of equal length.

In the above figure, ABCD is a rectangle where

AB = CD and BC = AD

Each interior angle is 90°.

Now, perimeter of a rectangle = 2(length + breadth)

Area of rectangle = length * breadth

Area,perimeter and diagonals

The rectangle is a quadrilateral, with equal opposite sides.

Area = Length × Breadth

Perimeter = 2(Length + Breadth)
