There are two formulas for the area of a hexagon. The first only needs the side length; the second also uses the apothem.
When you only know the side length, use this formula:
If you also know the apothem, you can use either of these equivalent expressions:
Both expressions are equivalent and give the same result.
In a regular polygon like the hexagon, the apothem is the shortest distance from the center to any side. The image below shows it clearly:
