Aaron is having rain gutters installed around the perimeter of his roof. How much will he spend if he is charged $3.50 per foot?

$294.35

Step-by-step explanation:

left and right side of the house: 15 ft + 15 ft = 30 ft

top part of the house: (20 ft - 12 ft = 8 ft) 8ft + 9.6 ft + 7.5 ft = 25.1

bottom part of the house: (20 ft - 15 ft = 5 ft) 15 ft + 5 ft + 4. 5 ft + 4.5 ft = 29

30ft + 25.1ft + 29ft = 84.1

84.1 ft x $3.50 = 294.35
