    -12.5

    Step-by-step explanation:

    To easily get the area of the parallelogram, we will label the vertices.

    A = 1, - 2 ... X1, y1

    B = 5,8 ... X2, y2

    C = 3,3 ... X3, y3

    D = 0,8 ... X4, y4

    Before that, let me state that:

    The Area of a parallelogram is defined as:

    1/2 det (X1 (y2 - y3) + X2 (y3 - y1) + X3 (y1 - y2)

    In the order from the question:

    A = (-2 (8-3) + 5 (3-3) + 3 (3-8)) / 2

    A = - 2 (5) + 5 (0) + 3 (-5)

    A = - 10 + 0 - 15 / 2

    A = - 25/2

    A = - 12.5
