a rectangle has a length that is four more than three times the width. If the perimeter is 126 feet, find the length and the width

  • math -

    L = 3W+4
    2(L+W) = 126
    2(3W+4 + W) = 126
    2(4W+4) = 126
    8(W+1) = 126
    W+1 = 15.75
    W = 14.75
    L = 3W+4 = 48.25

    2(14.75+48.25) = 2(63) = 126
