Important to note that centers of the arcs/circles are not given as the vertices A or B or midpoint of CD respectively
(1) ABCD is a square of area 64
--> We do not know the centers of the arcs/circles shown. So, there is no way we can calculate the areas of the arcs/circles --> Insufficient
(2) Product of the diagonals of the square ABCD is 128
--> We do not know the centers of the arcs/circles shown. So, there is no way we can calculate the areas of the arcs/circles --> Insufficient
Combining (1) & (2),
Still no information on the dimensions of arcs/circles --> Insufficient
