==================
Another opinion:
I've never done one of these before, but I tried this one,
and for my answer, I got 140.5 cm2.

It is at the intersection of the hexagon's lines of symmetry, i.e. the middle! It is the midpoint of any diameter.
It probably is a regular hexagon. Take the Apothem (The distance from the center to a side) and multiply by one half and by the perimeter. if the sum of interior angles of a polygon is 120 then (n-2)180=120==>n=8/3 which is impossible
if r = perpendicular distance center of hexagon to a side, and r^2 = r squared, then AREA = 6x r^2 x tan 30 degrees = 3.464 r^2 or if R = distance center of hexagon to a corner, AREA = 3 R^2 sin 60 = 2.598 R^2
P=perimeter s=sides h=altitude (distance from the center to a side at a right angle) A=1/2aP or A=1/2(6s x a) Edit - If the hexagon is regular, the area can be found by this formula: 3s^2 * 3^(1/2) / 2 Where s=side length of the hexagon and in this case squared and 3^(1/2)=square root of 3

From each vertex to its opposite vertex. These will be centered on a shared point at the center of the hexagon. Each complete line will be a line of symmetry for the hexagon.

No, it is the distance from the center of the polygon to the centre of one of its sides.
A Apothem
P=perimeter s=sides h=altitude (distance from the center to a side at a right angle) A=1/2aP or A=1/2(6s x a) Edit - If the hexagon is regular, the area can be found by this formula: 3s^2 * 3^(1/2) / 2 Where s=side length of the hexagon and in this case squared and 3^(1/2)=square root of 3
That is called the apothem. The definition is: An Apothem is the distance from the center of a regular polygon to the midpoint of a side
The distance from the center to a corner is equal to one of the sides. If you add up the lengths of all 6 sides, that is the circumference.
The particles will meet at the center of the hexagon after traveling a distance of half the side length a/2, so the time taken for one particle to reach the center from a corner is t = (a/2) / v. Since there are six particles and they all start moving simultaneously, the time for them to meet at the center is t = (a/2) / v.
