Expt2. Python Program to find the area of triangle

Aim: Implement a program to find the area of triangle

Algorithm:

1.Start

2.Read three sides (a,b,c) 
3.calculate s=(a+b+c)/2 
4. calculate area=sqrt(s*(s-a)*(s-b)*(s-c)) 
5.print area 

6.Stop

Program:

# Three sides of the triangle a, b and c are provided by the user

a = float(input('Enter first side: '))

b = float(input('Enter second side: '))

c = float(input('Enter third side: '))

# calculate the semi-perimeter

s = (a + b + c) / 2

# calculate the area

area = (s*(s-a)*(s-b)*(s-c)) ** 0.5

print('The area of the triangle is %0.2f' %area)

Output:

Enter first side: 5

Enter second side: 6

Enter third side: 7

The area of the triangle is 14.70
