Answer 1

Answer:

129 square foot

Step-by-step explanation:

Step 1: Convert height of the door to inches

Height of the door = 10 feet 8 inches

1 feet = 12 inches

10 feet = y inches

Cross Multiply

y = 120 inches

Height of door in inches = 120 + 8 =128 inches

Step 2: Find the surface area of one side of the door

Surface area = length x width

length = 128 inches

width = 145 inches

Surface area = 128 x 145

Surface area = 18560 inches

Step 3: Convert surface area from inches to square foot

Surface area = 18560 inches

1 square foot = 144 inches

         y           = 18560 inches

Cross multiply

144y = 18560

y = 18560/144

y = 128.89 rounded off to 129 square foot.

Therefore, you should report 129 square foot surface area to the hardware store.
