  1. Set up the two equations in the two vzriables, length (L) and width (W).
    They are:
    L - W = 6
    and
    L W = 84

    Then solve them, using algebra.

  3. I made two mistakes. I was very sloppy reading the problem,. and apologize.

    This is how algebra is done. If you don't use this method, you will have to keep trying pairs of numbers until you get as pair that works,

    L = 2W + 6 since the length L is 6 more than twice the width, W.

    2(L + W) = 84 since that is the perimeter

    2L - 4W = 12
    2L + 2W = 84
    6W = 72
    W = 12
    L = 30
