Answer :

Side of square ABCD = radius of sector C - BXD = 20 cm

Area of square = (side)2 = 2002 = 400 sq.cm

Area of shaded region inside the square = Area of square ABCD - Area of sector C - BXD   76 sq.cm

Radius of bigger sector = Length of diagonal of square ABCD Area of the shaded regions outside the square = Area of sector A - PCQ - Area of square ABCD = A(A - PCQ) - A(ABCD)  628 – 400

228 sq.cm

total area of the shaded region = 86 + 228 = 314 sq.cm.
