Please help how do i find the area of the shape?

Orlov [11]

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: $A= \frac{1}{2}(\pi r^2)$

For the triangle, here is the formula for area: $A=\frac{1}{2}(bh)$

Then, add.

So,

Triangle:

$A=\frac{1}{2}(9*12)$

$A=54$

Semicircle:

$A=\frac{1}{2}(\pi 6^2)$

$A=18\pi$

Your answer is $Area = 54 + 18\pi$
