An integer n (3 ≤ n ≤ 100), representing some quantity or size.
A list of n tuples, each containing two integers, where each integer is between 0 and 10000.

### Example Input:

```
4
0 0
10000 0
10000 10000
0 10000
```

### Function Signature:
Write a function f(n, coordinates) that takes in the input.
```python
def f(n: int, coordinates: List[Tuple[int, int]]):
    '''
    n: an integer
    coordinates: a list of tuples, each containing two integers
    '''
```
