the cost of leveling a square lawn at ₹15 per square metre is ₹19935 .find the cost of fencing the lawn at 22 per metre​

Answer 1

Answer: Total cost of fencing the lawn is Rs. 3208.07.

Step-by-step explanation:

Since we have given that

Cost of levelling a square lawn at Rs. 15 per square = Rs. 19935

Cost of levelling a square lawn at Rs. 22 per square be 'x'.

So, Area will become

Area=\frac{Total\ cost}{Cost\ per\ m^2}\\\\Area=\frac{19935}{15}\\\\Area=1329\\\\Side\times Side=1329\\\\Side=\sqrt{1329}\\\\Side=36.45\ m

So, perimeter of square becomes 4×side

So, it becomes = 4 × 36.45 = 145.82 m

Since Cost of per m = Rs. 22

So, Cost of fencing becomes

22\times 145.82\\\\=Rs.3208.07

Hence, Total cost of fencing the lawn is Rs. 3208.07.
