find the area of the square, the triangle and the circle at the top....but remember to take half of the area for the circle since its not a whole circle.

Start by finding the area of the semicircle, it should be (pi*6^2)/2. Then find the area of the rectangle, it should be 12*7. Then find the base of the triangle, it should be 15 squared minus 12 squared, then unsquare the answer to get the base. The area of a triangle is Base*height/2. Then add them all together, its long but I hope it helps.
