2. Length of a rectangle = Area ÷ breadth.
3. ℓ = A ÷ b.
4. Similarly, when we need to find breadth of a rectangle we need to divide area by length.
5. Breadth of a rectangle = Area ÷ length.

## How do you find length Width Height and Area?

Multiply the length by the width and you’ll have the square feet. Here’s a basic formula you can follow: Length (in feet) x width (in feet) = area in sq. ft.
