Answer: 69.25m^2
Explanation: you first find the area of the triangle, and then the area of the half circle on the bottom, and add them both together.
Area of triangle:
A = 1/2(bh) —> A = 1/2(10*6) —> A = 30m^2
Area of half circle:
A = 1/2(pi*r^2) —> A = 1/2(3.14*5^2) —> A = 39.25
(Radius is 5, because diameter is 10m, so diameter divided by 2 is 5)
Total area: 30m^2 + 39.25m^2 = 69.25m^2
