Step-by-step explanation:

The length of the roof in the blueprint is half the length of the real roof but in inches instead of feet. Therefore, for the blueprint to be proportional, the width has to be half the width of the real roof:


W_{\text{blueprint}}=(18)/(2)=9

Answer:

The width of the roof in the blueprint is 9 inches
