Question

jake measured a hotel and made a scale drawing. the scale of the drawing was 8 inches : 7 feet. if the actual length of a room in the hotel is 21 feet, how long is the room in the drawing? inches

Explanation:

Step1: Set up proportion

Let $x$ = drawing length.
$\frac{8 \text{ inches}}{7 \text{ feet}} = \frac{x}{21 \text{ feet}}$

Step2: Solve for $x$

Multiply both sides by 21:
$x = \frac{8 \times 21}{7}$

Step3: Calculate the value

$x = 8 \times 3 = 24$

Answer:

24 inches
