Rectangles

area = length (l) x bredth (b)

Another way to find the area of a rectangle is to multiply its length by its width.

The formula is: area = length × width

We can rearrange this formula to find the length or the width:

length = area ÷ width

width = area ÷ length

Question

What is the length of this rectangle?

Area = 56cm squared and height = 7cm
Answer

The area is 56cm2 and the width is 7cm, so the length is 56 ÷ 7 = 8cm
