Answer:
4 square units
Step-by-step explanation:
If you draw a vertical line down the middle of the square, you divide it into two triangles that are congruent to the smaller triangles shown in the figure. Hence each of those triangles has an area of 1/2 square unit.
After you have divided the square as above, you see that two smaller triangles are identical in area to the larger triangles. So, each of those has an area of 2(1/2) = 1 square unit.
Then the total of areas is ...
2 small triangles + square + 2 large triangles = 2(1/2) + 1 + 2(1) = 4
The area of the rectangle is 4 square units.

sales $3012
commission 3.5% of sales: 0.035 * 3012 = $105.42
Raquelle's total earnings: $290 + 105.42 = $395.42

Step-by-step explanation:
Given:
A circle with a radius of 5 cm sits inside a 11 cm x 11 cm rectangle.
Question asked:
What is the area of the shaded region as shown in the figure ?
Solution:
First of all calculate area of circle and then area of rectangle:-
![Area\ of\ cirle=\pi r^{2}](https://tex.z-dn.net/?f=Area%5C%20of%5C%20%20cirle%3D%5Cpi%20r%5E%7B2%7D)
![=\frac{22}{7} \times5\times5\\ \\ =\frac{550}{7}\\ \\=78.571\ cm^{2}\\](https://tex.z-dn.net/?f=%3D%5Cfrac%7B22%7D%7B7%7D%20%5Ctimes5%5Ctimes5%5C%5C%20%5C%5C%20%3D%5Cfrac%7B550%7D%7B7%7D%5C%5C%20%20%5C%5C%3D78.571%5C%20%20%20cm%5E%7B2%7D%5C%5C)
<u>As here length an width both are 11 cm, we can say that this is a square.</u>
<u />![Area\ of\ square=(Side)^{2}](https://tex.z-dn.net/?f=Area%5C%20of%5C%20square%3D%28Side%29%5E%7B2%7D)
![=11\times11=121\ cm^{2}](https://tex.z-dn.net/?f=%3D11%5Ctimes11%3D121%5C%20cm%5E%7B2%7D)
Now, area of shaded region = Area of square - Area of circle
= 121 - 78.571 = 42.429 ![cm^{2}](https://tex.z-dn.net/?f=cm%5E%7B2%7D)
Therefore, the area of the shaded region will be 42.43 ![cm^{2}](https://tex.z-dn.net/?f=cm%5E%7B2%7D)
