A regular hexagon has perimeter 72m. Find the area

Sagot :

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:

[tex]\begin{gathered} A=\frac{3\sqrt{3}s^2}{2} \\ Where: \\ s:Measure\text{ of a side of the regular hexagon} \end{gathered}[/tex]

We know that the measure of any side of our regular hexagon equals 12m, so, we could just replace in the equation:

[tex]A=\frac{3\sqrt{3}(12m)^2}{2}\rightarrow A=\frac{3\sqrt{3}(144m^2)}{2}\rightarrow A=216\sqrt{3}m^2[/tex]

Simplified, that's about 374.1 m2.
