The area of the shaded region in the figure given below is

`(a^2 )/(2) ((pi )/(2) -1)` sq. units

`a^2 ( pi-1 )` sq . Units

`a^2 ((pi)/(2) -1) ` sq . Units

`(a^2)/(2) - (pi -1) ` sq . Units

`A cap (B cup C)`

`A cup (B cap C)`

`A cap (B-C)`

`A-(B cup C)`

`A nn (B uu C)`

`A uu (B nn C)`

`A nn (B -C)`

`A - (B uu C)`
