Since the formula for the area of a rectangle is length × width = height, we can divide the area by the length to get the width.

175.5 ÷ 13 = 13.5

And since the width is one dimensional, the answer is A.

Hope this helps!
Area = length x width
Given:  length = 13 , area = 175.5

175.5 = 13 x width
width = 175.5 ÷ 13 
width = 13.5 feet

The width is 13.5 ft (Answer A)
