Question

Answer

Square DEMH has area 18 x 18 = 324.
Quadrant BFK = (pi x 18 x 18)/4 = 254.34

The small square in the middle is darker because it overlapped.
If we sum the square and quadrant, the small square is counted twice.
So we need to subtract it to get the shaded area.

Area of shaded area = 324 + 254.34 - 25 = 553.34 cm2
