Question

The cost of harvesting a square field at ₹ 900 per hectare is ₹ 8100. Find the cost of putting a fence around it at ₹ 18 per meter.

Answer 1

As, the rate of the harvesting = ₹ 900 per hectare

And, the cost of harvesting = ₹ 8100

So, the area of the square field = \(\frac{8100}{900}\) = 9 hectare

So, side = 300m

Now, perimeter of the field = 4 x side

= 4 x 300

= 1200 m

Since, the rate of putting the fence = ₹18 per m

So, the cost of putting the fence = 1200 x 18 = ₹ 21,600
