B. 20 inches
To find the perimeter in the scale drawing, you would take the actual perimeter of the pool and divide it by the scale factor.
Actual perimeter = 2(24 feet) + 2(36 feet) = 48 feet + 72 feet = 120 feet
Scale factor from feet to inches = 120 feet / 8 inches = 15
Perimeter in the scale drawing = 120 feet / 15 = 20 inches
