Question

A Pest control company sprays insecticide around the perimeter of a 180 ft by 180 ft building. If the spray costs $.11 per foot, how much did the job cost to the nearest dollar?

Answer 1

P = 4a.....this is the perimeter of a square
P = 4(180)
P = 720 ft

and if the spray cost 0.11 per ft......720 * 0.11 = 79.20 rounded to the nearest dollar is $ 79 <==
