A contractor needs 54 square feet of brick to construct a rectangular walkway. The length of the walkway is 15 more than the width Write an equation that is the answer?
Ans: I L = length and W = width, then L = W + 15;
area = LW = 54, so (W+15)W = 54, i.e. WxW + 15W - 54 = 0;
solving this gives W = 3, so L = 18.
