Question

A map of a forest uses a scale of 1 inch = 15 miles. The dimensions of the map are 8 inches by 14.5 inches. What is the actual area of the forest?

A) 116 square miles
B) 1740 square miles
C) 5062.5 square miles
D) 26100 square miles

Answer 1

D. When working with scales, always remember to convert. The dimensions of the actual forest become 8 X 15 and 14.5 X 15. To calculate the area, now just do: (8 X 15) X (14.5 X 15), which equals 26100.

Answer 2

The dimension from 8 inches to actual size is 8 * 15 = 120. 14.5 inches to actual size is 14.5 * 15 = 217.5.

Then, you multiply 120 to 217.5 to get 26100 square miles.

The answer is D.
