Program for Surface Area of Octahedron

Given the sides of Octahedron then calculate the surface area.

Examples:

Input  : 7
Output : 169.741

Input  : 9
Output : 280.59

An regular octahedron has eight faces, which are all in the shape of equilateral triangles.The area of an octahedron is 2 multiplied by the length of an edge squared multiplied by the square root of three.

Formula:
Surface area= 2*(sqrt(3))*(side*side)
