Question

A contractor is pouring a concrete driveway. The perimeter is 108 ft. What length will the driveway be if the width is 14 ft.?. . The driveway is ____ feet long.

Answer 1

The Perimeter = 2 L + 2 W
108 = 2 L + 2 · 14
108 = 2 L + 28
2 L = 108 - 28
2 L = 80
L = 80 : 2
L = 40 ft
Answer: the driveway is 40 feet long.
