Question

A rectangle dog pen has an area of 108 square feet. The width of the pen is 9 feet. What is the length?

Answer 1

Answer: 12

Step-by-step explanation:

Since area = length x width

108 square feet = length x 9 feet

To do this, you have to figure out what number times 9 is 108.

108/9 = 12

So, the answer is 12.

Answer 2

Area = Length times width. So L = area/width. With this we make the equation 108/9 = length, so the width is 12 feet.
