    P = Perimeter

    L = Length

    W = Width

    L = 1 + 2W

    W = W

    Rectangle has 4 sides

    2 (1 + 2W) + 2W = 62

    Distribute

    2 + 4W + 2W = 62

    Simply

    2 + 6W = 62

    Solve for W

    6W = 60

    W = 10

    Plug 10 in for W in the Length formula to find Length

    L = 1 + 2 (10)

    L = 1 + 20

    L = 21

    Check if wanted**

    2 (L) + 2 (W) = 62

    2 (21) + 2 (10) = 62

    42 + 20 = 62

    62 = 62

    :D
