The perimeter of a rectangle is 80 cm. it’s width is 4 cm. what is the length of the rectangle?

36.

This is because since the perimeter is all the sides added together, you have to subtract what you have and find the result.

Since the width is four, you’d double that and subtract the total from 80. That leaves you with 72. So divide that in 2 and you’ll get your length - 36.

Hope this helps!
