Question

A blueprint for an art gallery uses a scale of 1 in: 4 ft.

One of the rooms in the gallery measures 3 1/2 inches long on the blueprint.
How long is the actual room (in feet)?

Answer 1

14ft is the answer !!!

Answer 2

I'm not sure what picture you need, but this is a proportion problem.
1/4 = 3.5/x => x = 14 feet
