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).
