Area of all four sectors made by square and circle are equal.

And each sector have an angle of 90

0

And radius of circle is

2

12

cm=6 cm

Area of shaded region = Area of square ABCD −4× Area of one sector

⇒ Area of shaded region = Area of square ABCD − Area of circle with radius 6 cm

=12×12−π×6

2

cm
