Answer:
Do not listen to the other answer! Here is how you solve that.
Step-by-step explanation:
For the semicircle, here is the formula for area: [tex]A= \frac{1}{2}(\pi r^2)[/tex]
For the triangle, here is the formula for area:[tex]A=\frac{1}{2}(bh)[/tex]
Then, add.
So,
Triangle:
[tex]A=\frac{1}{2}(9*12)[/tex]
[tex]A=54[/tex]
Semicircle:
[tex]A=\frac{1}{2}(\pi 6^2)[/tex]
[tex]A=18\pi[/tex]
Your answer is [tex]Area = 54 + 18\pi[/tex]
