Question 7 - Past Year - 2 Mark Questions - Chapter 14 - Functions in python

Write a Python program using functions to calculate area of a triangle after obtaining its three sides.

Answer:

import math

def triangle_area (a,b,c):

    s=(a+b+c)/ 2

    ar=math.sqrt(s*(s-a)*(s-b)*(s-c))

    return ar

a=float(input( "Enter first side of the triangle: " ))

b=float(input( "Enter second side of the triangle: " ))

c=float(input( "Enter third side of the triangle: " ))

area=triangle_area(a,b,c)

print("The area of a triangle with sides ",a,", ",b,", ",c," is ",area)
