Please be more specific with your question. If you mean 2cm, then the area will be 12cm squared. If you mean 2m then the area will be 12m squared.
Let's draw a segment from the center of the hexagon to the middle of a side. This segment is called the apothem. Then use the 30-60-90 triangle rule. If half of a side is 15, that means the apothem...
Six
Ahexagon = 3sqrt(3)s2/2 = 3sqrt(3)(82)/2 = 96sqrt(3)
a hexagon can only have 6 sides
