Answer:
272.5
Explanation:
dotted line of the circle = 12 because this whole thing is a parallelogram + half a circle. so diameter for the 1/2 circle is 12
so that means radius = 6, which is 1/2 of the diameter
circle area = π*r² = 36π
1/2 of it = 18π = 56.5
parallelogram area = base * height = 24 *9 =216
total 216+56.5
