Answer: Perimeter = 38
=============================================
Work Shown:
A = area of rectangle = 88
W = width = 11
L = unknown length
A = L*W
88 = L*11
11L = 88
L = 88/11 ... divide both sides by 11
L = 8
The length is 8
----------
P = perimeter of rectangle
P = 2L+2W
P = 2(L+W)
P = 2(8+11)
P = 2(19)
P = 38
