    Answer:

    First choice

    Step-by-step explanation:

    first solve for each side of the triangle using slope formula:

    y2-y1/x2-x1    ex: (x1, y1) (x2, y2)

    this solve for all the lengths. AB, BC, CA

    then solve for the area of the triangle:

    A=1/2 b*h

    A=1/2 2* 1/2

    A=1/2 or .5
