A contractor is pouring a concrete driveway. The perimeter is 108 ft. What length will the driveway be if the width is 12
ft.?

Respuesta :

Answer:

42 ft

Step-by-step explanation:

Perimeter is the same as w+w+l+l or 2w+2l

width= 12 ft and there are 2 widths, so 12x2= 24ft

108-24= 84

84/2 = 42 ft
