Solution: a = side of the square = 10, r = radius of the quarter circles = 5. I connect the middle of the sides of the square and get a square in the middle with the side length √(r²+r²) = √(2r²) = r*√2. The area of this square is 2r². Now: blue area = 2*(area of the whole circle - area of the square in the middle) = 2*(π*r²-2r²) = 2r²*(π-2) = 2*5²*(π-2) = 50*(π-2) ≈ 57.0796
I calculated the required area but in a different way.😊😊

Solution:
a = side of the square = 10,
r = radius of the quarter circles = 5.
I connect the middle of the sides of the square and get a square in the middle with the side length √(r²+r²) = √(2r²) = r*√2. The area of this square is 2r². Now:
blue area = 2*(area of the whole circle - area of the square in the middle)
= 2*(π*r²-2r²) = 2r²*(π-2) = 2*5²*(π-2) = 50*(π-2) ≈ 57.0796
