√2 cm. It passes through A and B as shown in fig. Find area of shaded region

Answer 1

where is the diagram through which we can see the shaded region??

Answer 2

Answer:

Step-by-step explanation:

Given

L=20,b=10

Radius of semicircle

10√2

Area of rectangle

L*b

20*10

200

Area of the semicircle

1/2 pi r^2

1/2*22/7*10√2*10√2

1*11/7*100*2

1*11/7*200

1*2200/7

314.285...

Area of shaded region=area of semicircle-area of rectangle

= 314.285-200

=114.285...
