Question

The length of a rectangle is 8 centimeters, and the area of the rectangle is 72 square centimeters. What is the width of the rectangle?

Answer 1

The width if the rectangle is 9 sq. cm.

Explanation:

a = wl, which means area equals length times width, so to find the width when you have the length and area you need to divide the area by the length.

72/8 = 9

This exact method will also work if you have the width and not the length.

Hope this helps!
