On a blueprint for a house, the scale is 1/2 in = 4 feet. If the length of a room is 32 feet, how long is it on the map?

Step-by-step explanation:

We can use a proportion to solve this.

Let x = how long the room is on the map

So, x/32 = 0.5/4

Cross multiply

4x = 16

Divide by 4

x = 4

Check

4/32 = 0.5/4

4 x 4 = 32 x 0.5

16 = 16

Our answer is correct
