Answer:
C
Step-by-step explanation:
The figure consists of a semicircle of radius 6 m, and a triangle with base of 12 m and height of 5 m. The base of the triangle is 12 m since it has the length of the diameter of the circle, or twice the 6-m radius.
A = area of semicircle + area of triangle
A = (1/2)πr² + bh/2
A = (1/2)π × (6 m)² + (12 m)(5 m)/2
A = (18π + 30) m²
