Answer 2

Answer:

3 inches

Step-by-step explanation:

We can use proportions to solve.  Put the map on top and the real life size on bottom.

1 inch             x inches

------------- = -------------

4 ft                  12 ft

1 * 12 = 4 * x

Divide each side by 4

12/4 = 4x/4

3 =x

3 inches
