Question

Manny is building a rectangular garden in a community center. His garden will be next to an existing 12 ft. fence. The gardener has a total of 44 ft of fencing. How long will the garden be if the width is 12 feet?

Answer 1

16 feet

Explanation:

You want to know the length of a garden that is 12 ft wide and will be fenced on 3 sides using 44 ft of fence. The remaining side already has a 12 ft fence.

Perimeter

The width of the garden is 12 feet. There is already a 12-ft fence to add to the 44 ft of fencing that Manny has. The total perimeter is ...

P = 2(L +W)

12 +44 = 2(L +12)

28 = L +12 . . . . . . . . . divide by 2

16 = L . . . . . . . . . . . . subtract 12

The length of the garden is 16 feet.
