Question

the cost of fencing a square lawn at Rs 14 per metre is Rs 28000.find the cost of mowing the lawn at Rs 54 per 100m square.

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
Answer.

Answer 2

Cost of moving 250000 square metres of the lawn is Rs. 135000
