Question

How to calculate the area of a triangle using Heron’s formula in Python

Answer 1

import math

def heron_area(a: float, b: float, c: float) -> float:
    # Calculate the area of a triangle using Heron's formula.
    s = (a + b + c) / 2.0  # semi-perimeter
    
    return math.sqrt(s * (s - a) * (s - b) * (s - c))

def main():
    a, b, c = 6, 9, 13

    # Check validity of triangle
    if a + b > c and a + c > b and b + c > a:
        area = heron_area(a, b, c)
        print(f"Area of the triangle = {area:.4f}")
    else:
        print("Invalid triangle sides!")

if __name__ == "__main__":
    main()



'''
run:

Area of the triangle = 23.6643
