Answer:
72 inches
Step-by-step explanation:
The area formula is ...
A = LW . . . . . . the product of length and width
The perimeter formula is ...
P = 2(L+W)
You are given the width and the area, so L can be found as ...
128 = L×4
32 = L
Using this in the perimeter formula gives ...
P = 2(32 +4) = 2(36) = 72
The perimeter is 72 inches.
