Answer 2

Step-by-step explanation:

1) Length of the hockey field = 91m 40cm = 9140 cm

Breadth of the hockey field = 55m = 5500 cm

Length of the boundary = 9140 + 5500 = 14640 cm = 146m 40cm.

2) Outer circle has longer boundary and inner circle has shorter boundary. So Valsamma has to cover more length. Therefore Valsamma loses the race.
