let the radius of the circle and length of a rectangular field be 2x and 7x respecrively
it is given circumference of the circle =176m
=2πr=176
substituting value of r from above
2π(2x)=176
x=176/4π
44/π
x=14m
know length is 7x which equls 7×14=98m
2(length of the field+width of the field)=322
l+b=161
from above l=98m
thefor b=161-98=63m
