In a scale drawing 0.5 inch represents 3 feet if the same scale is used how many inches will be needed to represent 24 feet?

Answer 1

This can be solved with a simple proportion problem.

You set it up like this:

.5/3 = x/24

Then you can cross multiply to get:

(.5)24 = 3x

The simplify to get:

12 = 3x

Then divide both sides to get:

4 = x

So, you need 4 inches to represent 24 feet using this scale.
