Answer:

The length of the longer side is 45 inches

Step-by-step explanation:

Let the shorter side of the rectangle = b

Let the longer side of the rectangle = l

One side of a rectangle is 11 inches shorter than four times another side.

l = 4b - 11

Perimeter of a rectangle is given as:

P = 2(l + b)

The perimeter is 118 inches

118 = 2[(4b - 11) + b]

118/2 = 4b + b - 11

59 = 5b - 11

5b = 59 + 11

5b = 70

b = 70/5

b = 14

l = 4b - 11

l = 4(14) - 11

l = 45

The length of the longer side is 45 inches
