    Answer: Width = 3 and Length = 14

    Step-by-step explanation:

    Length = 2W + 8

    Width = W

    Perimeter = 2 (width) + 2 (length)

    34 = 2W + 2 (2W + 8)

    Distribute

    34 = 2W + 4W + 16

    Combine like terms

    34 = 6W + 16

    Solve for W

    34 - 16 = 6W

    18 = 6W

    W = 3

    Substitute 3 in for W in Length equation.

    L = 2 (3) + 8 = 14
