The length of the top of rectangular-shaped deck is 6 meters longer than its width. If the area of the top deck is 72 square meters what is its lengths in meters?

The width is 6m and the length is 12m

1) set up equation

2) distribute

3) put all values on one side

4) factor

5) - 12 cannot be a width, so 6 is the width

6) plug the width (6) back into the equation from step 1
