Let side of the square be 's'
Given , s²=60025 m²
s=±245 = 245
Perimeter of square = 4s = 4*245 = 980 m
Speed = 18 × 5/18 m/s = 5m/s
Time = 980/5 s = 196 s

Area of the square feild = 60025m^2
Length of one side = 245 m
Distance needed to covered by the man = 4 (245)
= 980m
= 980/1000
= 0.98km
Speed of the cyclist = 18 km/h
Time to be taken = distance / speed
=0.98/18
=0.054 h
