Answer:
Approximately 201 squared inches.
Explanation:
So, the composite figure is made up of a square and a semi-circle. The square has side lengths of 12 and the semi-circle has a radius of 6.
The total area of the figure would be the area of the square plus the area of the semi-circle. Thus, find the area of each individual figure.
Square:
The area of a square is given by:
![A=l^2](https://img.qammunity.org/2021/formulas/mathematics/middle-school/hdtc5lkk57llhj8ry4a4afdm78e1tvf4vo.png)
Where l is the side length.
Substitute 12 for l:
![A=(12)^2\\A=144\text{ in}^2](https://img.qammunity.org/2021/formulas/mathematics/college/elyug0bm2x7vash71k2b6rxmkz10liypzk.png)
So the square is 144 square inches.
Semi-circle:
The area of a semi-circle is given by:
![A=(1)/(2)\pi r^2](https://img.qammunity.org/2021/formulas/mathematics/college/3o5meqzxorq5mg5dpperhjtg6bcanf0gvw.png)
Substitute 6 for r and 3.14 for π:
![A=(1)/(2)(3.14)(6)^2\\ A=56.52](https://img.qammunity.org/2021/formulas/mathematics/college/4pjz61mydr5j0vm5pdcnrj6637s9c8pv45.png)
Therefore, the total area is:
![TA=144+56.52\\TA=200.52\text{ in}^2\approx201\text{ in}^2](https://img.qammunity.org/2021/formulas/mathematics/college/ndbicaa5ws9jcsuozlmu66mwnwbft3f29s.png)
