# How to find the area and perimeter of a rectangle?

A Rectangle is a four sided-polygon, which has equal opposite sides and 4 interior right angles.

## Answer: The area of a rectangle = length × breadth, perimeter of a rectangle = 2 × (length + breadth).

Let us see an example of using these formulas

## Explanation:

Use the formula mentioned below to find the area and perimeter of a rectangle.

- area of a rectangle = length × breadth
- perimeter of a rectangle = 2 × (length + breadth)

Find the area of a rectangle of 4 units of length and 5 units of breadth

Area of the rectangle = 4 × 5 = 20 square units

Perimeter of the rectangle = 2 × (4 + 5) = 18 units
