The cost of levelling a square lawn at Rs.15 per metre square is Rs.19,935 find the cost of the fencing the lawn at Rs.2.2
metres

Answer 1

Total cost of leveling a square lawn at the rate of Rs. 15 per square meter = Rs. 19935

So, area of the square lawn = Total cost/Cost per square meter

= 19935/15

Area of the square lawn = 1329 sq m

Area of square = Side*Side

So, each side of square lawn = √1329

Each side of square lawn = 36.45 m

Now, 

Perimeter of the square lawn = 4*Side

= 4*36.45

Perimeter of the square lawn = 145.8 m

Cost of fencing the square lawn = 22 per meter

Total cost of fencing the square lawn = 145.8*22

Total cost of fencing = Rs . 3207.6

Answer 2

3207.6 rupees is the final cost of fencing the lawn
