Best answer

Cost of fencing the lawn Rs 28000

Let l be the length of each side of the lawn. Then, the perimeter is 4.

We know:

Area of the square lawn = 500 x 500 = 250000 m2

Cost of moving 100m2 of the lawn = Rs 54

Cost of moving 1 m2 of the lawn = \(Rs\frac{54}{100}\)

∴ Cost of moving 250000 m2 of the lawn = \(\frac{250000\times 54}{100}\) = Rs 135000
