Answer 2

SOLUTION:-

Given,

Area of the square field= 60025m²

Length of each side of the square field

=) √60025

=) 245m

We know that, perimeter of the square:

=) 4× 245

=) 980m

Therefore,

980/1000km

It is also given that, the man is cycling at a speed of 18km/h.

Therefore,

$Time = \frac{Distance \: travelled}{Speed} \\ \\ = > \frac{ \frac{980}{1000} }{18} \\ \\ = > \frac{980}{1000 \times 18} hr \\ \\ = > \frac{980 \times 60 \times 60}{18000}sec. \\ \\ = > 98 \times 2 \: seconds \\ \\ = > 196 \: seconds \\ = > 3 \: minute \: 16 \: seconds$

Hope it helps ☺️
