Question

The scale factor of the blueprint of a gymnasium to the actual gymnasium is 1in/15ft. The area of the flow on the blueprint is 114in2.

What is the area of the actual gymnasium?

Answer 1

1/15=144/x
Cross multiply
X=2,160

Gymnasium=2,160 ft2

Answer 2

B) 25, 650 ft^2

If the ratio is 1:15, then the measurements of each side of the actual gym are 15 times greater than the scale's. So the areas would have a ratio of 1:225. 114 times 225 is equal to 25, 650
