The perimeter is the sum of the outside dimensions.
b1 = 87 - 32 - 14 - 13 = 28 in.
Area = (32 + 28) /2 x 12 = 60/2 x 12 = 30 x 12 = 360 square inches.
Divide area by the amount 1 can covers:
360 / 50 = 7.2 cans, round up to 8 cans are needed.
5/6 = 5 ÷ 6 = 0.8333
8/9 = 8 ÷ 9 = 0.8888
so 8/9 is bigger.
