OC. 112.5 inches by 135 inches
OD. 22.5 inches by 25.5 inches

Answer 1

Answer:

A. 2 inches by 2.4 inches

Step-by-step explanation:

1 inch (drawing) represents 7.5 ft (real)

To go from the real dimensions to the drawing dimensions, divide the real number by 7.5 and change from ft to inches.

15 ft:

15/7.5 = 2

Change ft to in.

15 ft (real) becomes 2 in. (drawing).

18 ft:

18/7.5 = 2.4

Change ft to in.

18 ft (real) becomes 2.4 in. (drawing).

Answer: 2 inches by 2.4 inches
