Write a program to obtain side from user and print the area of equilateral triangle with side a .

Q. Area of an equilateral triangle can be computed as √3/4 * a² where a is its side. Write a program to obtain side from user and print the area of equilateral triangle with side a.

Answer :-

import math
side = float(input("Enter the side of Triangle :- "))
area = math.sqrt ( 3 ) / 4 * side ** 2
print ("Area of Triangle :-",area)

Output :-

Enter the side of Triangle :- 2
Area of Triangle :- 1.7320508075688772
>>> 

Enter the side of Triangle :- 100
Area of Triangle :- 4330.127018922193
