Rectangle ABCD is inscribed in the circle shown.

If the length of side $\overline{AB}$ is

what is the area of the shaded region?

$a.\ 40.8\quad b.\ 53.1\quad c\ 72.7\quad d \ 78.5\quad e\ 81.7$

well to start with the common triangle of 12 5 13 gives us the diameter of 13

area of the circle is $\pi \left(\frac{13}{2}\right)^2=132.73$

area of {circle - retangle)=$132.73-60 =72.7$ which is c

typos maybe:unsure:
