~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Each triangle has the hypotenuse of 20 units (same as the radius) and one leg (horizontal)
of 12 units. Hence, each vertical leg is 16 cm (3-4-5 right angled triangle).
Hence, the area of the two triangles is = 192 square units.
The area of the square is = 256 square units.
The area of the segment is = = 164.0608 square units.
The total area is the sum of parts 192 + 256 + 164.0608 = 612.0608 square units (approximately). ANSWER
