your answer is 24sq. units.
what I did to find this answer is I got out some graphing paper, and graphed it ( I haven't been taught any other way) and then I connected the lines to make the shape. then I found the area of the invisible rectangle that was formed around it, and divided it by two... because the shape ABCD is half of the area of the rectangle formed. ... I hope you get what I'm trying to say.
