Quizplus · Accepted Answer

The equation for the area of a rectangle is length × width = area. Let the width be x inches. Then, the length is x + 3 inches. The equation becomes x(x + 3) = 304. Solving this quadratic equation (x^2 + 3x - 304 = 0) gives x = 16 as the positive solution, which represents the width of the rectangle.
