A regular hexagon is comprised of six equilateral triangles.  The "base" of each triangle is just 10 cm (in this case) and the "height" is sqrt(102 - 52).

 

Can you take it from here?

I understood the first part but Im confused at "is sqrt(10^2 - 5^2)". Is that the formula to solve?

sqrt(102 - 52) → sqrt(100 - 25) → sqrt(75) → 5*sqrt(3)

 

This is the height of the black(?) line going from the centre to the side in your picture.

The area of a triangle, of course, is given by half base times height.

The two red lines and the purple(?) line between them form an equilateral triangle. Find the area of this and multiply by six to get the area of the hexagon.
