# The length of Cassie’s family room is exactly half the length of her bedroom. Both rooms are rectangular, and the area of the two rooms is the same. If Cassie’s family room has a length of L and a width of W, which of the following represents the width of her bedroom?

W/2

Explanation

The length of the bedroom (the longer room) is 2L. Since the two areas both equal $$\text {L} \times \text {W}$$, the width of the bedroom must be W/2.
