Note:Equilateral Triangle: A Triangle is called equilateral triangle if length of 3 sides of it are equal.Example: a = 10, b = 10, c = 10;

So we ask the user to input value of the side only once.

Formula To Calculate Perimeter and Area of Equilateral Triangle

Perimeter = a + a + a;i.e., Perimeter = 3 * a;

Area = ( ( sqrt(3) / 4 ) * pow(a, 2));

where a is the value of side of the Equilateral Triangle.
