Question

James is putting a fence around his square yard. The area of his yard is 100 square feet. How much fencing does James need in total to go around all

four sides of his yard?
O 10 ft
O 20 ft
O 40 ft
O 80 ft

Answer 1

40 ft.

Explanation:

Because James's yard is a square, we can take the square root of the area to find the side length. The square root of 100 is 10, so we know that one side of his yard will require 10 feet of fencing. Since the yard has 4 sides, we simply need to do 4 * 10 = 40 ft of fencing.

Hope this helps!
