Question

stanley measured a county park and made a scale drawing. the picnic area, which is 120 yards long in real life, is 270 inches long in the drawing. what scale did stanley use? 9 inches : yards

Explanation:

Step1: Set up proportion

Let the number of yards for 9 inches be $x$. We know that 270 inches in the drawing represents 120 yards in real - life. So the proportion is $\frac{270}{120}=\frac{9}{x}$.

Step2: Cross - multiply

$270x = 120\times9$.

Step3: Solve for $x$

First, calculate $120\times9 = 1080$. Then $x=\frac{1080}{270}=4$.
