Giselle a pendant on her necklace that is the shape of a regular hexagon. On the pendant, there are lines for the center of each
Nina [5.8K]

Answer:

The area of the pendant is <u>12 square centimeters</u>.

Step-by-step explanation:

<u><em>The question is incomplete, so the complete question is below:</em></u>

Giselle a pendant on her necklace that is the shape of a regular hexagon. On the pendant, there are lines for the center of each vertex that divided it into congruent triangles. Each triangle has an area of 2 square centimeters.

What\ is\ the\ area\ of\ the\ pendant?

Now, to get the area of pendant.

In the hexagonal pendant there are congruent triangles that are divided from the lines of the center of each vertex.

<u><em>Each triangle's area</em></u> = 2 square centimeters.

As, we see in the figure below there are six congruent triangles in the hexagonal pendant.

Hence, <u><em>the number of triangles</em></u> = 6.

So, to get the area of pendant we multiply each triangle's area by the number of triangles:

2\ cm^2\times 6\\\\=12\ cm^2.

Therefore, the area of the pendant is 12 square centimeters.
