Hi,

Hexagon is a six-sided polygon.

Regular polygon means all sides and all angles are equal.

So regular hexagon is a 6-sided polygon with all sides and all angles are equal.

There are six equilaterals triangles with side length as β€œ2”.

Area of an equilateral triangle = (√3/4)*(side)^2
= (√3/4)*(2)^2 = (√3)

So, area of six equilaterals triangles = 6√3

So the answer is E.

Hope this helps.

The area of an equilateral triangle with side-length a is (√3/4)a^2. So, the area of an equilateral triangle with side-length 2 is (√3/4)2^2 = (√3/4)4 = √3. Thus, the area of a regular hexagon with side-length 2 is 6√3.

Therefore, the answer is E.
Answer: E
