Question

the length of the scale drawing of the fence is 7 inches. find the length of the actual fence in feet. start by finding the length of the actual fence in inches. scale: 1 to 60

Explanation:

Step1: Use scale - factor to find actual length in inches

Since the scale is 1 to 60, the actual length in inches $L_{inches}$ is the scale - factor times the length on the drawing. So $L_{inches}=7\times60 = 420$ inches.

Step2: Convert inches to feet

We know that 1 foot = 12 inches. Let the length in feet be $L_{feet}$. Then $L_{feet}=\frac{420}{12}=35$ feet.

Answer:

35 feet
