Perimeter of lawn = 28000/14 = 2000 cm

side length = 2000/4 = 500 cm

area = (500)² = 250000 = 250×100 cm²

**cost will be Rs 54×250 = Rs 13500**

side length = 2000/4 = 500 cm

area = (500)² = 250000 = 250×100 cm²

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
