An integer L (1.0 ≤ L ≤ 500.0), representing some length.
A decimal R (1.0 ≤ R ≤ 10.0), representing some count.
An integer N (3 ≤ N ≤ 100), representing some quantity.
N pairs of integers (Xi, Yi) (-1000 ≤ Xi ≤ 1000, -1000 ≤ Yi ≤ 1000), where each pair represents coordinates.

### Example Input:

```
4.0 2.0 8
-1 0
5 0
5 -2
7 -2

### Function Signature:
Write a function f(inputs) that takes in the input as a list of tuples. 
def f(inputs: List[Tuple[float, float, int, List[Tuple[int, int]]]]): 
    ''' 
    inputs: a list of tuples, where each tuple contains:
        L: a decimal
        R: a decimal
        N: an integer
        coordinates: a list of tuples of integers
