## What is the perimeter formula?

The formula for the perimeter of a rectangle is often written as P = 2l + 2w, where l is the length of the rectangle and w is the width of the rectangle. The area of a two-dimensional figure describes the amount of surface the shape covers.

## What is length and width?

Length is the distance from one end to the other end of an object, while the width is the distance from side to side.

## How do you find the length and area of a rectangle?

Let’s discuss how to find length or breadth when area of a rectangle is given. When we need to find length of a rectangle we need to divide area by breadth. Length of a rectangle = Area ÷ breadth. ℓ = A ÷ b. Similarly, when we need to find breadth of a rectangle we need to divide area by length.

## What is the length of a rectangle?

The length of a rectangle is the longest side, whereas the width is the shortest side. The width of a rectangle is sometimes referred to as the breadth (b).
