Q.
'PQRS' is a rectangular park. A rhombus 'cdef' is inscribed in it by joining the midpoints of sides PQ, QR, RS, and SP. Person 1 walks along the path P→ Q→ R→ S→ P and another person 2 walks along path c→ d→ e→ f→ c.
If person 2 wants to catch person 1 at point 'e', then what path should person 2 follow and what will be the length of it?
It is given that PQ = 20 m and QR = 10 m.
