Area of shaded region = Half the area of square.
i.e., (12*12)/2 = 72 sq. units

area of yellow sector inside circle=144*pi/8=56.54862 sq cm
therefore area of both sectors= 113.09724 sq cm
area outside the circle= 144-113.09724 = 30.90276 sq cm
thus yellow area outside circle = 15.45138 sq cm
hence whole yellow area= 56.54862+15.45138=72 sq cm

without calculations
since white area and yellow area are same each=0.5*144=72 sq cm

This can be solved visually by looking at the shaded bisected area of the upper left hand corner and concluding that
it forms 1/2 of the square.

thus: 1/2*144 = 72
