    |dw:1328578695789:dw| (all the triangles are equal) so i divided 328 in half to get the one side. the other side i subtracted 550-328, then divided it by 2

    then i just did normal area for a triangle 1/2BH and so A=1/2(164)(111) for the square, i just did base times height, so 328x328 i added those two together and got my area

    welll did you multiply the area of the triangle by two? that way your not adding one triangle to the area of the rectangle your adding the area of both triangles
