Question

Dean is helping his mom make a fence for their rectangular vegetable garden. First, they measure the sides and find that it is 20 feet long and 40 feet wide. Then, they buy fencing from the hardware store. If the store sells fencing in 4-yard packages, how many packages do Dean and his mom need?

Answer 1

10 packages

Explanation:

To find the number of 4 yard packages for the fencing, we need to find the perimeter of the fence.

Perimeter = 2*(20 + 40)

Perimeter = 2*60 = 120 feet

*It is important to note that the perimeter is in feet and the packages are in yards*

4 yards = 12 feet

120 / 12 = 10 packages
