Answer
G) $90=w(2w+3)$
Work Step by Step
The area of a rectangle is the length multiplied by the width.
Responses H and I can be eliminated since the width (w) is not a factor.
We are told the length is 3 feet longer than twice its width.
Twice the width is $2w$.
$2w+3$ is three more than twice the width, so response G is correct.
