    Think you can take a picture or draw the shape?

    Okay. If you're ever given something that seems unnecesary complicated, always try to take it down to something very simple. If you were given a similar problem, but it was just a rectangle or a triangle on a similar grid, could you do it?

    uhh maybe. would it just be multiplying the sides?

    if that is the case then can't i just make that one shape in 2 shapes.. and find out the different areas?

    Right. For a rectangle to get the area you multiple the side lengths. For a right triangle you multiple the side lengths and divide by two Does this picture help at all? http://puu.sh/idZon/229348e264.png

    If you can find the area of each individual shape and add them up, you'll get the whole area

    So for the rectangle it would be 6x6=36 right?

    and for the triangle i would do... 3x3 divided by 1/2? which would be 4.5?

    Which triangle are you looking at? I think you might've miscounted the side length

    Sometime's it's important to look back at the bigger picture. There are 3 triangles and one rectangle

    so... 3x4 div by 1/2= 6 3x6 div by 1/2= 9 6x6 div by 1/2= 18

    Oh. Keep in mind that you only look at the bases of a right triangle for its area. So a triangle that looks like this http://puu.sh/ie16I/1549b72568.png Has bases 1x6, so it's 6x1 div by 2= 3
