answered-by-expert Expert Answer
When a square is inscribed in a circle, the diagonal of a square must be equal to the diameter of circle.
Let the side of square be s.
Then,
Diagonal of square = V2 a
Thus, we have:
V2 a = 16 cm
a = 16/V2 cm = 8V2 cm
 
Thus, area of the square = (8 V2 cm)2 = 128 cm2
