Question

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

Answer 1

Find the area of the lawn:

Area = 19935 ÷ 15 = 1329 m²

Find the length of the lawn:

Area = Length²

Length² = 1329

Length = √1329

Find the perimeter:

Perimeter = 4 x Length

Perimeter = 4x √1329 = 4√1329 m

Find the cost of fencing:

1 m = Rs 2.2

4√1329 m = 2.2 x 4√1329 = Rs 320.81

Answer: The cost of fencing is Rs 320.81

Answer 2

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

answere is 3207.6
