Answer: The answer is rs582.
Step-by-step explanation:Let the radius of inner track be r.
According to question,
220=π*2*r
On solving the equation we get the radius of inner track= 35m
Now, the radius of outer boundary= 35+7m=42m
The circumference of the outer boundary is= 2*π*42m = 264m
Cost of fencing= rate*circumference
=2*264rs
=528rs
