Question

find thearea of the shaded region in Fig.3, where areas drawn with centres A,B,C
and D intersect in pairs at mid-points P, Q, R and S of the sides AB, BC, CD and DA
respectively of a square ABCD of side 12 cm (Use = 3.14)

​

Answer 1

Answer:

answer 30.96 cm². Please mark me as brainliast. Hope it helps.

Step-by-step explanation:

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

2

=144−113.04 cm

2

=30.96 cm
