Cost of fencing= Rs. 14/mt.

Total cost = rs.28000

Length of each side of square= 28000/14 =2000 m

* So length of each side of square lawn = 2000m

Area of square lawn = side X side

= 2000 X 2000 = 4000000 M2

Total cost = 40000 X 54/ 100= Rs. 21600- Ans.

So total cost of mowing the land = Rs. 21600
