# 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
