What is the perimeter distance of 1200 hectares?

Answer 1

Any distance from 12280 metres upwards.

If the area in question is in the form of a circle, it will have a perimeter of approx 12280 metres.

To see how the perimeter can increase without limit, let x be any positive number.

Let y = 12000000/x.

Then a rectangle with length x metres and breadth y metres will have an area of 1200 hectares. Its perimeter will be 2(x + y) metres which is more than 2x metres. But x can have any value so 2x can be made as large as you like. And the perimeter will be [at least, slightly] larger still.
