Quizplus · Accepted Answer

The width of the frame can be found by setting up the equation for the area of a rectangle, A = lw, where l = w + 3 (since the length is 3 cm more than the width). Substituting the given area, 154 = w(w + 3). Solving this quadratic equation (w^2 + 3w - 154 = 0) gives w = 11 cm as the width of the frame.
