    Answer:

    A = 216 cm^2

    P = 80 cm

    Step-by-step explanation:

    l = 12

    w = 18

    As the object is rectangular, the area is height * width and the perimeter is

    2(height + width) as there are two of each side.

    12 * 18 = 216 U^2   U = unit of measurement, I would presume for a poster you use cm so its 216 cm^2

    12 + 18 = 40

    40 * 2 = 80 cm
