Bunuel I do not know if the perimeter of the shaded region can be found out. I am having trouble in understanding the concept. Could you please help me here?

Hi,

The perimeter will be divided into four parts

1. left hand of section(shaded area) = r(larger circler) - r(smaller circle)

2. right hand of section = r(larger circler) + r(smaller circle)

3. length of arc (bigger circle) = x/360* (2pi*r larger circle)

4. length of arc (smaller circle) = x/360* (2pi*r smaller circle)

Regards
