Answer :

Let R be the radius of outer circumference and r be the radius of inner circumference

Outer circumference of circular field = 2π R

And inner circumference of circular field = 2π r


Length of Outer circular field – length of inner circular field = 132m

circumference of circular field - circumference of circular field = 132 m

2π (R- r) = 132m

R – r = 21 m

This is the radius of the circular path

Given, area of path = 14190 m2

π (R- r)2 = 14190

(R-r) = 4515

Radius of circular path = 67.19 m
