The sum of the areas of the shaded regions is the area of the circle minus the area of the
square. The area of the circle is equation where equation Therefore, this area is equation. To
find the area of the square, you need the length of one of the sides. Since the diagonal of the square is d,
each side equals equation. Therefore, the area of the square is equation. The
sum of the areas of the shaded regions is equation which equals equation.
The correct answer is (A).
