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 will be Rs 54×250 = Rs 13500

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
