Step-by-step explanation:
This is a composite figure consisting of two shapes.
The first thing you should do is find the area of the semicircle.
To find the area of the semicircle, use the following formula and plug in your numbers:
Divide the diameter of the semicircle by 2.
8/2 = 4
Now, use this: 3.14(4)^2
To find the area of the triangle, use 8*12/2 (base x height divided by two)
Add both areas to get your answer.
