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.
