Answer:
23.5 cm^2
Step-by-step explanation:
First calculate the "rectangle" with the half-circle filled in
9*3 = 27
Then calculate the half-circle using the formula for the area of a circle [tex]\pi r^{2}[/tex], then dividing it by half
3.14 * 1.5 * 1.5 / 2 = 3.5325
Subtract the area of the half-circle from the area of the rectangle
27-3.5325
= 23.4675
= 23.5 (cor. to the nearest half unit)
