Answer 2

Answer:

Rs.9020

Step-by-step explanation:

Circumference of the inner circle =.2πr

π=22/7 r=140m

=2*22/7*140

=2*22*20

=880m

Circumference of the outer circle= 2πr

π=22/7 r=147m

=2*22/7*147

=2*22*21

=924m

Cost of fencing the path=Rs.5 per/meter

Length of fence=Circumference of inner circle+circumference of the outer circle

=880+924

=1080m

Cost of fencing=1080*5

=9020Rs.
