The area of a square field is 60025 m2. A man cycles along its boundary at 18 km/h. In how much time will he return to the starting point?

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
