Question

If the scale factor is 5:8, and the actual width of the model is 20 feet, what is the model width?

Answer 1

If the scale factor is 5:8, it is the same as 5/8.

In order to calculate the width of the model, just multiply its actual width by the scale factor, as follow:

width of the model = (20 ft)(5/8) = 12.5 feet

Hence, the width of the model is 12.5 feet
