A billboard is 2.5 times as long as it is wide. The area of the actual billboard is 2,250 square feet. A scale drawing is made of the billboard and the area of the scale is 160 square inches. What is the scale used in the scale drawing?

Answer 1

the area grows as the square of the linear scale. So the scale is

√(160in^2/2250ft^2)
= √(160/32400 in^2)
= √(1/2025)
= 1:45

Answer 2

This is a completely incorrect answer to this problem.
