Vince made a scale drawing of the middle school. He used the scale 5 inches : 8 feet. If the gym is 45 inches wide in the drawin

Scale drawings are used to show an actual image using lesser dimensions.

The width of the actual gym is 72 feet

The scale is given as:

$Scale = 5\ inches : 8\ feet$

Represent the width of the actual gym with w, so, we have the following equivalent ratio

$45\ inches : w = 5\ inches : 8\ feet$

Cancel out the common units

$45: w = 5: 8\ feet$

Express as fraction

$\frac{45}{w} = \frac{5}{8\ feet}$

Cross multiply

$5w = 45 \times 8\ feet$

Divide both sides by 5

$w = 9\times 8\ feet$

$w = 72\ feet$

Hence, the width of the actual gym is 72 feet
