Final answer:

The approximate area of the land in hectares can be calculated using the formula A = πr², where r is the radius of the circle.

Step-by-step explanation:

The area of a circle can be found using the formula A = πr², where r is the radius of the circle.

In this case, the diameter of the circle is given as 200m. The radius is half of the diameter, so the radius would be 100m.

Using the formula A = π(100)², we can calculate the approximate area of the land.
