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

Explanation:

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

The scale is 1 to 60, which means actual length = scale - drawing length×60. Given scale - drawing length is 7 inches. So actual length in inches = 7×60.
$7\times60 = 420$ inches

Step2: Convert inches to feet

Since 1 foot = 12 inches, to convert 420 inches to feet, we divide by 12. So actual length in feet=$\frac{420}{12}$.
$\frac{420}{12}=35$ feet

Answer:

35 feet
