Answer: 61.5 cm²

To find : Area of shaded region

Step by step explanation: to find the area of it, we need to subtract the area of circle from the area of square.

Area of circle= \large πr^{2} πr

2

= \large \frac{22}{7}

22

× 3.5 × 3.5

= 38.5 cm \large ^{2}

2

Area of Square = Side \large ^{2}

2

side = 10

so, 10 \large ^{2}

2

= 100 cm

Are of shaded region= 100-38.5

=61.5 cm \large ^{2}
