There's no way to figure out the area of the shaded region directly, but you can figure out the area of the non-shaped region and subtract. Since the radius of the circle is 5, you know that the area of the circle is 25π. Subtract that from the area of the square, 100, to ge...
You can see that the area of the shaded region is just the difference of the area of the big circle (radius b) and the area of the small circle (radius a). The area of the small circle is just a^2, and the area of the big circle is just b^2. So the difference is:π b^...
