➜ Area of square = L²

= ( 10 )²

= 100 cm²

➜ Area of circle = 2 π r

= 2 × 22 × 3.5

7

= 2 × 22 × 35

7 10

= 2 × 22 × 5

10

= 22 cm²

➜ Area of shaded part = Area of square - Area of circle

= ( 100 - 22 ) cm²

= 78 cm²

Answer :- 78 cm²

I hope it helps you.

Answer 2

Answer:

Area of square. = Side(2)

= 10cm(2)

=. 100cm(2)

Area of circle. = 2πr

=. 2×22/7×3.5cm

=. 22cm(2)

Area of shaded part = Area of sq. -

Area of circle

=. (100-22)cm2

=. 78cm(2)
