We are given that the perimeter of the rectangle is 88 m. Therefore, P = 88. We substitute this value into the perimeter equation determined in the previous step. P = 21+ 2w 882/+2w We then solve the resulting equation for 1. 88 = 2/+2w 1 = Next, we substitute this expression for / into the area equation determined in the previous step and expand the result.. A = lw A = -w + Recalling that area must be greater 0, we note that this equation is valid when 0 < w
