Question

My sister is buying new carpet for her bedroom floor. The length of the bedroom is 13 feet. The area of the bedroom is 175.5 square feet. How wide is my sister's bedroom?

A. 13.5 ft

B. 13.5 ft 2

C. 162.5 ft 2

D. 198.5 ft 2

Answer 1

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!

Answer 2

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)
