Answer:
62 ft
Step-by-step explanation:
To find the perimeter, we need to know the length and width. We are given the area and length, but not the width. The given information is sufficient to find the width, using the area formula.
A = LW
228 ft^2 = (12 ft)W
(228 ft^2)/(12 ft) = W = 19 ft
The perimeter of a rectangle is twice the sum of length and width:
P = 2(L +W)
P = 2(12 ft +19 ft) = 62 ft
The perimeter of the rectangle is 62 feet.
