Answer 2

Heyy mate ❤✌✌❤

Here's your Answer.....

⤵️⤵️⤵️⤵️⤵️⤵️⤵️

Area of smaller Semicircle = pie × r^2 / 2

=> 22/7 × 15 × 15 /2

=> 11/7 × 15 × 15

=> 353.57cm^2

Area of Larger Semicircle = pie × r^2 /2

=> 22/7 × 20 × 20/2

=> 3.14 × 20 × 10

=> 628cm^2


Therefore, Area of Semicircle = 628 - 353.57

=> 274.43cm^2.

Area of two semicircle = 274.43 × 2

=> 548.86cm^2 --------------(1)

Area of Bigger Rectangle = l × b

=> 60 × 40

=> 2400cm^2.

Area of smaller Rectangle = l × b

=> 50 × 30

=> 1500cm^2.

Area of shaded region = 2400 - 1500

=> 900cm^2.-----------(2)

Therefore,
Area of shaded region = 548.86 + 900

=> 1448.86cm^2.
