    8 = 2 (l + w)

    l = 3w

    Replace l in first equation with 3w.

    8 = 2 (3w + w)

    Combine like terms.

    8 = 2 (4w)

    Multiply.

    8 = 8w

    Divide both sides by 8.

    w = 1

    The width is equal to 1.

    Replace the value of w with 1.

    l = 3w

    l = 3 (1)

    l = 3

    The length is equal to 3.
