Question

the cost of levelling a square lawn at rupees 15 per square metre is rupees 19935 find the cost of fencing the lawn at rupees 22 per metre​

Answer 1

Step-by-step explanation:

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

Area of the lawn = Total cost/Cost per square meter

= 19935/15

Area of the square lawn = 1329 Sq m

 

Area of the square = Side*Side

So, each side of the square = √1329

Each side of the square lawn = 36.45 m

Now, 

Perimeter of the square lawn = 4*Side

Perimeter = 4*36.45

Perimeter of the square lawn = 145.8 m

Cost of fencing the square lawn = Rs. 22 per meter

Total cost of fencing the square lawn = 145.8*22

= Rs. 3207.6

So, total cost of fencing the square lawn is Rs. 3207.6
