Answer:

B. x^2-10

Step-by-step explanation:

Your are trying to find the shaded region

You can see that the x by x square would be "full" if not for the 2 by 5 chunk that has been taken out of it

Therefore you can find the area by subtracting the 2 by 10 "chunk" out of the total area of the x by x square

Equation:

(x*x)-(2*5)

x^2-10

The answer is B

$\\ \rm\bull\rightarrowtail x^2-3x-6x+27-7=0$

$\\ \rm\bull\rightarrowtail x^2-9x+20=0$

$\\ \rm\bull\rightarrowtail x^2-5x-4x+20=0$

$\\ \rm\bull\rightarrowtail x(x-5)-4(x-5)=0$

$\\ \rm\bull\rightarrowtail (x-4)(x-5)=0$

$\\ \rm\bull\rightarrowtail x=4,5$

We have a circle of radius 5 m inside a square of side 10 m. The shaded area is:

$A_{\text{Shaded}}=A_{\text{Square}}-A_{\text{Circle}}$

Now, we calculate the area of the square and the circle:

$\begin{gathered} A_{\text{Square}}=10^2=100m^2 \\ A_{\text{Circle}}=\pi\cdot5^2=25\pi m^2 \end{gathered}$

Finally, the shaded area is:

$A_{\text{Shaded}}=100-25\pi\approx21.5m^2$
