    two parallelograms will not work as in a parallogram the opposite sides need ot be of equal length. You can approach it multiple ways. Easiast in my opinion would be to just make 4 triangles.

    yep, look for some shapes you recognize and that you know how to find the area of . Going further it will look like.

    Hope from here u can proceed... after you add up the areas, you get the final answer, the area of the entire shape. :)

    both height and base is 3 so it would be 1/2x3x3=4.5

    you can use distance formula, right

    yes but idk which lines is the base and height for the triangle after i do the distance formula and start to do the area

    ok it will be complicated go for base*height formula... calc height and base

    draw perpendicular from B to the base. coordinates are mentioned.. you will get trough distance formula

    According to my calc, these are the final values .... Area of ABC= 13.5 Area of AGF=4.5 Area of CGHD=36 Area of HED=3 Adding up gives final answer.... @king_kong_killer
