At one point, she believed GMAT wasn’t for her. After scoring 595, self-doubt crept in and she questioned her potential. But instead of quitting, she made the right strategic changes. The result? A remarkable comeback to 695. Check out how Saakshi did it.

One way to look at this problem is you have two intersecting sections of two circles. My approach here would be to calculate the arc area for each section of the circle and sum them, subtract the overall area of the square (which will leave you with only the area of the overlap), and then calculate the final area in question.
Arc area = angle/360 * pi * R^2
Arc area = 90/360 * pi * (1)^2
Arc area = 1/4 Pi
Since the arc areas are identical, we can just multiply by 2 to get 1/2 Pi = total area of two arcs.
Area of shaded region = area of two arcs - area of square = 1/2 Pi - (1)^2
Area of unshaded region = 1 - (1/2 Pi - 1) = 2 - 1/2 Pi.
Hope that helps.

Hi
Not sure I understand. If you get the area of the arc inside the circle and multiple that by two, that's a LOT more than what you need to account for. You're only taking the partial area of the arc, but as per your calculations, wouldn't you be taking the full arc into account?
