    ok. Choose a spot near the middle and draw arrows going down up, left, and right|dw:1442234895246:dw|

    it is a trapezoid, do you know the formula?

    then plug in your side lengths to the formula and there is your area

    Wait. How do i find the sides.

    I just put dots in my graph to draw the trapezoid.

    When i look at it, it looks like trapezoid.

    But i don't know yet the exact numbers of those sides.

    well we have D(-4,-4), E(4,-4), F(2,3) and G(-2,3) for our points so if we connect those points we get our sides. You can simply count the distance between these points if you draw this on graph paper

    you actually do not need the last side length, as the formula for a trapezoid is h{(a+b)/2 where a and b are the bases, 4 and 8. To find the height, all you do is count the vertical distance from a to b.
