    Well, we know that P = 2(l+w) and A = lw, right? with me so far?

    A = lw = 154, so we can solve for L by dividing both sides by W

    L = 154/w, then we can plug this into the perimeter equation and solve for w

    ok, so if L = 154/W, and P = 2(L+W), we substitute in "154/W" for L, can you tell me what you get after you do that?
