Question

a scale drawing for a construction project uses a scale of 1 inch= 4 feet. On the model, the dimensions for the family room are 7.5 inches by 12 inches. what is the area of the actual family room

Answer 1

1 inch = 4 ft

so 7.5 inches = (7.5 * 4) = 30 ft
and 12 inches = (12 * 4) = 48 ft

A = L * W
A = 30 * 48
A = 1440 square ft <=
