As, the man is cycling along the perimeter, we need to find it first.
Length of sq field = √60025 (since l=a²) = 245m
Now,
Perimeter = distance = 4×245 = 980 m
Speed = 18 km/h = 5m/s
Therefore, time = 980/5 = 196 sec = 3 mins 16 secs.

Now,

Speed = 18 km/h = 5m/s
Therefore, time = 980/5 = 196 sec = 3 mins 16 secs.
