A regular hexagon has six equal sides:
If you notice, a regular hexagon has exactly six equilateral triangles inside of it.
So, to find the area we could find the area of a triangle and then multiply this result by 6. This seems to be a little bit complicated to do, so, there's a formula to find the area of a regular hexagon, which is:
We know that the measure of any side of our regular hexagon equals 12m, so, we could just replace in the equation:
Simplified, that's about 374.1 m2.
