Question
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?

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