At the center of a square of side 10 cms, another square of side 20 cms is hinged by one of its corners so that it can rotate freely about the hinge. Initially , the sides of the hinged square are parallel to the other fixed square . The hinged square is rotated slowly through an angel of 45 degrees. The area common to the squares.
