The area of the hexagonalbaseis givenby the formulafor the area of a regularpolygon.Sinceeachside

of the hexagonmeasures cm, the perimeteris or cm. The apothem,or perpendiculardistance


to the centerof the hexagonis cm.


Usingthe PythagoreanTheoremto find the slantheightof eachlateraltriangle.

Now find the area of eachtriangle:
