Step-by-step explanation:
Given that,
Area of the square field = 60025 m2
Length of each side of the square field =
= 245 m
We know that,
Perimeter of the square = 4 × sides
= 4 × 245
= 980 m
=
km
It is also given that, the man is cycling at a speed of 18 km/h
Therefore,
Time =
=
=
hr
=
sec
= 98 × 2 sec
= 196 sec
= 3 min 16 sec
