Josh wants to put a fence around his rectangular garden. The garden is 6 feet by 15 feet. How much fencing must he purchase?

A. 30 feet

B. 35 feet

C. 42 feet

D. 47 feet

Solution

C. You need to calculate the perimeter of the garden. The perimeter is the sum of all the sides, or use the formula P = 2l + 2w. You are given the dimensions of 6 feet and 15 feet. Substitute that information into the formula.

   P = 2(6) + 2(15)

P = 42 ft
