Question:

The perimeter of a square and a regular hexagon are equal. The ratio of the area of the hexagon to the area of the square is:

Options:

$2\sqrt{3}:1$

$2:\sqrt{3}$

$3\sqrt{3}:2$

$\sqrt{2}:3$

Correct Answer:

$2:\sqrt{3}$

Explanation:

Let the side of the square a
Perimeter of the square =4a

Let the side of the hexagon =b
Perimeter of the hexagon =6b
Given, 4a=6b
Thus, a=3b/2
Area of the square =a2
Area of the hexagon =(33)b2/2
Now, Area of hexagon : Area of square = (33)b2/2 : a2
(33)b2/2 : (3b/2)2
⇒ (33)b2/29b2/4
⇒ 33/2 : 9/4
⇒ 2 : 3

The correct answer is Option (2) → $2:\sqrt{3}$
