### What is the area of a regular hexagon with side length of 40cm?

To find the area of a regular hexagon with side length of 40cm,
consider that since it is regular, then it consists of 6
equilateral triangles of side 40cm. Half of each of those triangles
is a right triangle. By the pythagorean theorem, we know that if
the hypotenuse is 40cm, and one side is 20cm, then the other side
is the square root of (40cm squared - 20cm squared) or about
34.64cm. That makes the area of each of those 12 right triangle to
be about 692.8cm, so the total area of the hexagon is about
8313.8cm.
