Python program to accept side of Equilateral Triangle and find its area

Write a Python program to accept the side of Equilateral Triangle and find its area 

A = (√3)/4 × side2

import math
a=float(input("Enter the Length of Side"))
area=(math.sqrt(3)/4)*(a**a)
print("Area of Triangle is : ",area)

Enter the Length of Side5
