Question

Troy 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 Troy and his mom need?

Answer 1

10 Packages

Explanation:

The rectangular vegetable garden has a dimension of Length 20 feet and Width 40 feet.

Perimeter of a Rectangle=2(L+W)

=2(20+40)=2(60)=120 feet

Since the store sells fencing in 4-yard packages, let us convert our perimeter to Yards.

x Yard =120 Feet

Cross Multiply

x=40 Yards

The Perimeter =40 Yards

Therefore the number of Packages which Troy and his Mom needs:

Perimeter of the Garden÷Length Per Package

=40÷4

=10 Packages

Troy and his mom would need 20 Packages of Fencing.

To be able to conclude, we conver
