    3 inches by 12 inches

    Step-by-step explanation:

    Length = L

    Width = W

    LW = 36

    L = 36/W

    2 (L + W) = 30

    2 (36/W + W) = 30

    36/W + W = 15

    36 + W² = 15W

    W² - 15W + 36 = 0

    (W - 3) (W - 12) = 0

    W = 3 or W = 12

    Therefore the dimension is 3 inches and 12 inches.
