Because 2500m^2 is the area of square field
so Side of the square park= √(2500)^2 = 50m
Now perimeter of this park = 4a = 4×50 = 200m
and he hv to round it 5 times, so distance that he have to walk = 200×5 = 1000m = 1km
We have given the speed = 4km/h
We know that:-
Speed = Distance/Time
4 = 1/Time
Time = 1/4 hour = 15min
So, he will walk the distance in 15min.
thankyou buddy.
Hope you are helped. :-)
