Question

the area of a square lawn is 1296 sq.m. find the cost of fencing the lawn at the rate of rupees 200 per metre​

Answer 1

Solution:-

Total cost of fencing the square lawn = Rs. 28000

Cost per meter = Rs. 14

Perimeter of the square lawn = 28000/14

Perimeter of square lawn = 2000 meter.

Now, each side of the square lawn = perimeter/4

= 2000/4

Each side of square lawn = 500 meter

Area of the square lawn = 500 × 500

Area of the square lawn = 250000 sq m

Cost of mowing the lawn = Rs. 54 per 100 sq m

Total cost of mowing = (250000*54)/100

Total cost of mowing = Rs. 135000
