Expert Answer:

The extended alternate side forms a triangle with the included side of the hexagon.

It's a equilateral triangle with side 2 cm.

So we have such 6 equilateral triangles in the star.

The area of the star shaped region = Area of hexagon + area of 6 equilateral triangles

  = 2 x 6 x Area of one equilateral triangle,

  = 12 x 22x 3/4 = 123 cm2
