Answer: 69.8 m

Step-by-step explanation:

Given: The radius of the circular line = 11m

The distance covered by the person is given by the circumference of the circular line.

The circumference of the circular is given by :-

$\text{Circumference}=2\pi r$, where r is the radius of the circular line.

$\\\Rightarrow\ \text{Circumference}=2(3.14)(11)=69.8\ m$

Therefore, the distance covered by the person is 69.8 m.
