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)
