Two identical squares of side length 11 cm are kept one above another such that the square above completely overlaps with the square below. Now if the square above is rotated by 45 degrees about its center, what is the ratio of the area common to both squares to the remaining area?Now bang your brain and do share solution. this one ate my head for more than a hour!

1) 1 + root 2
2) 1 upon (1 + root 2)
3) (root2 - 1) upon (2 x root 2)
4) (2 x root2 - 1) upon (2 x root 2)

• 2) 1 upon (1 + root 2)
