Given: 
s=390 cm

*Note: I will use two different ways to solve the area of hexagon.

Solutions:
1st Method:

Use the Area formula of Hexagon: 

A=3√3/2 × s²
A=3√3/2 × 390²
A=395167.4 cm²

2nd Method:  
Use the formula for Area of a regular polygon:
*Note: n is the number of side of a polygon and s is the length of side. 
Since our polygon is hexagon and has 6 sides, our n is 6.

A=ns²/4tan(180°/n)                
A=6(390)²/4tan(180°/6)  
A=6(152100)/4tan(30°) 
A=912600/4√3/3
A=395167.4 cm²

The Area of Hexagon is 395167.4 cm
².
