Question

jasmine made a scale drawing of an office. the scale of the drawing was 4 inches : 3 feet. the desk is 8 inches long in the drawing. how long is the actual desk?

Explanation:

Step1: Set up proportion

Let $x$ be the actual length of the desk in feet. The scale is 4 inches : 3 feet, and the drawing - length is 8 inches. So the proportion is $\frac{4}{3}=\frac{8}{x}$.

Step2: Cross - multiply

Cross - multiplying gives us $4x = 3\times8$.

Step3: Solve for $x$

$4x=24$, then $x = \frac{24}{4}=6$.

Answer:

6 feet
