    divide irregular quadrilateral into rectangle and right triangle, find areas and add them up

    rectangle have the length of 857 and the width of 43
    so the area of the rectangle=857*43=36851

    one leg of the right triangle (altitude) are 865-43=822 and the other leg is 857
    the area of the right triangle= (1/2)822 *857=352227

    the area of the irregular quadrilateral=36851+352227=389078

    That's assuming that the sides labeled "255" and "43" are parallel.
