Answer by ewatrrr(10682)   (Show Source): You can put this solution on YOUR website!Hi, *note: P = 2*l + 2*w . question states 2*l + 2*w = 100ft l + w = 50ft . Let x be the length. The width would then be (50ft - x) . A = length *width A = x (50ft-x) . A = 50ft*x -x^2 . check your answer with one possibility (l=30ft, w = 20ft)
