Given,

Area of square field \[ = 60025{m^2}\]

Speed of cycle, \[v = 18km/hour\]

Solution,

Calculate the side of square field.

\[\begin{array}{l}{a^2} = 60025\\ \Rightarrow a = 245m\end{array}\]

Length of side of square field is \[245m\].

Speed of cycle,

\[v = 18km/hour\]

\[v = \frac{{18 \times 1000}}{{3600}}m/\sec \]

\[v = 5m/\sec \]

Calculate the time needs to complete one round.

\[{\rm{time = }}\frac{{{\rm{total}}\,{\rm{distance}}}}{{{\rm{speed}}}}\]

\[ = \frac{{4 \times 245}}{5}\]

\[ = 196\sec \]

Hence the time required to complete 1 round is \[196\sec \].
