Explanation:

Step1: Recall the formula for the perimeter of a rectangle

The formula for the perimeter \(P\) of a rectangle is \(P = 2\times(\text{length}+\text{width})\). Here, the length \(l = 54\) inches and the width \(w=36\) inches.

Step2: Substitute the values into the formula

First, find the sum of length and width: \(54 + 36=90\) inches. Then multiply by 2: \(P = 2\times90\).

Step3: Calculate the result

\(2\times90 = 180\) inches.

Answer:

D. 180 inches
