Answer:
Area = 126
Step-by-step explanation:
To figure out the area of the triangle, we must do 1/2 base times height. Which would be 1/2 of 6 times 6. Which is 18. Then to figure out the rectangle is just doing the width times the length and the same for the square. So 6 times 12 plus 6 times 6 equals 108. Then we add the triangles area and we come out with 108 plus 18 which equals 126.
