    Equation:

    (2w+2) + w + (2w+2) + w

    Combine Like Terms:

    6w+4=142 m (since that's our perimeter)

    Subtract 4 from both sides:

    6w=138

    Divide 6 from both sides

    w=23

    To find the length ... Plug in our width into our "length" equation

    (2 (23) + 2)

    46+2

    l=48

    Final Answer:

    w=23

    l=48
