Divide it into triangles!

OpenStudy (anonymous):

Is there a formula?

OpenStudy (potatoes.ramu):

I dunno this sorry :(

OpenStudy (anonymous):

There are 12 triangles in the figure, but idk if the height and given length is the same

Need to find apothem and area of this figure https://media.glynlyon.com/g_geo_2012/11/page56ar.gif

OpenStudy (lastdaywork):

Its a regular hexagon, right??

OpenStudy (anonymous):

I do not know...

Considering it to be a regular hexagon - |dw:1390054131826:dw| The triangle formed is an equilateral triangle. Try to find its area.

OpenStudy (anonymous):

What is the formula to find area of an equilateral triangle?

OpenStudy (lastdaywork):

You learnt quite a bit of trigonometry in previous question. So, find the altitude of the triangle. (Note: each interior angle is 60 degree)

OpenStudy (anonymous):

I really forgot...

OpenStudy (anonymous):

Oh wait I know its 2sqrt3

OpenStudy (anonymous):

for apothem

OpenStudy (lastdaywork):

Define apothem

OpenStudy (anonymous):

Distance from center of polygon to a side

OpenStudy (lastdaywork):

So, isn't altitude of the triangle (which you just calculated) is same as apothem ??

OpenStudy (anonymous):

Yeah haha thank you so much :)
