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  {{{2*(1/2)*12*16}}} = 192 square units.


The area of the square is  {{{16^2}}} = 256 square units.


The area of the segment is  {{{pi*20^2*(47/360)}}} = {{{3.14159*400*(47/360)}}} = 164.0608 square units.


The total area is the sum of parts  192 + 256 + 164.0608 = 612.0608 square units (approximately).    <U>ANSWER</U>
