Question

The area of a rectangle is 20 square units and its length is 5 centimeters. Find its perimeter

Answer 1

18 centimeters.

Explanation:

Since you already know the length (height) divide 20 by 5 = 4.

This gives you the width (4), add up all the sides ( 4 + 4 + 5 + 5).

The sum comes out to be 18.
