Answer: <u>105m²</u>
Formula for Area of Circle: A = π r²
so, A = 3.14 (6)² (I got 6 because radius is half the diameter)
Don't forget to divide the final area of the circle in half, because It's only a semicircle.
Formula for Triangle: A = 
so, A =  (again, the "6" is just the diameter divided in half which forms the base of ONE triangle.)
 (again, the "6" is just the diameter divided in half which forms the base of ONE triangle.) 
You need to multiply the final area of the triangle by 2 since there are 2 triangles.
