Question

In the scale used on a blueprint, 14 inch represents 3 feet. On the blueprint, what is the length of a room with an actual length of 24 feet? 1. 3/4 in 2. 2 in 3. 6 in 4. 8 in

Answer 1

Answer: 2in

Step-by-step explanation:

Hi, to answer this question we have to apply proportions:

The correct scale on the blueprint is : 1/4 inch represents 3 feet.

So, the proportion is: 1/4 inch/ 3 feet = (1/4) /3

For 24 feet:

x inches /24 feet = x/24

So:

(1/4)/3 = x/24

Solving for x (inches)

[(1/4)/3 ] (24) =x

x =2 inches
