Python program to find the area of a triangle
Let see python program to find the area of a triangle.
- In this example, we will ask the user to enter the length of three sides of a triangle.
- We will use Heron's formula to calculate the semi-perimeter.
- And Area = (s*(s-a)*(s-b)*(s-c)) ** 0.5 to calculate the area of the triangle.
- At last,print the area of the triangle to get the output.
Example:
a = float(input('Enter the length of first side: ')) b = float(input('Enter the length of second side: ')) c = float(input('Enter the length of third side: ')) s = (a + b + c) / 2 Area = (s*(s-a)*(s-b)*(s-c)) ** 0.5 print('The area of the triangle is %0.2f' %Area) You can refer to the below screenshot to see the output for the python program to find the area of a triangle.
The above code we can use to find area of a triangle in Python.

Python program to calculate area of a triangle using function
Now, we will see python program to calculate the area of a triangle using function.
- Firstly, we will import math module which will allow us to use the mathematical function like math.sqrt function.
- Now, we will define the function with three arguments using the def keyword as def Areaoftriangle(a, b, c).
- We will use Heron's formula to calculate the semi-perimeter.
- And Area = math.sqrt((s*(s-a)*(s-b)*(s-c)))to calculate the area of the triangle.
- The user will enter the three sides of the triangle a,b,c and we will pass those values to function arguments to calculate the area.
- At last,print is used to get the output.
Example:
import math def Areaoftriangle(a, b, c): Perimeter = a + b + c s = (a + b + c) / 2 Area = math.sqrt((s*(s-a)*(s-b)*(s-c))) print("The perimeter of traiangle = %.2f" %Perimeter); print("The Semi Perimeter of traiangle = %.2f" %s); print("The Area of a triangle is %0.2f" %Area) Areaoftriangle(8, 9, 10) You can refer to the below screenshot to see the output for python program to calculate the area of a triangle using function.
The above code, we can use to calculate area of a triangle using function in Python.

Python program to find area of a triangle given all three sides
Here, we will see python program to find the area of a triangle given all three sides
- Firstly, we will import math module which will allow us to use the mathematical function like math.sqrt function.
- We will ask the user to enter the length of three sides of a triangle and it will be stored in a separate variable.
- We will use Heron's formula for calculating the semi-perimeter which is s=(a+b+c)/2.
- And Area = math.sqrt(s*(s-a)*(s-b)*(s-c)) to calculate the area of the triangle.
- At last,print the area of the triangle to get the output.
Example:
import math a=int(input("Enter the length of first side: ")) b=int(input("Enter the length of second side: ")) c=int(input("Enter the length of third side: ")) s=(a+b+c)/2 Area=math.sqrt(s*(s-a)*(s-b)*(s-c)) print("Area of the triangle is: ",round(Area,2)) You can refer to the below screenshot to see the output for the python program to find the area of a triangle given all three sides.
This is the python program to find area of a triangle given all three sides.

Python program to find area of a triangle using class
Let's see python program to find the area of a triangle using class
- We will create a class called class sides.
- Another class called class A(sides) it has a method called def area(self) return(s*(s-self.a)*(s-self.b)*(s-self.c)) ** 0.5 which is the area of the class.
- Anobject for the class is created asobj = A(10,12,14).
- By using the object, the methodarea() is called.
- At last,print the area of a rectangle to see the output.
Example:
class sides: def __init__(self,a, b, c): self.a = a self.b = b self.c = c class A(sides): def area(self): s = (self.a + self.b + self.c)/2 return (s*(s-self.a)*(s-self.b)*(s-self.c)) ** 0.5 obj = A(10,12,14) print("Area of triangle : {}".format(obj.area())) You can refer to the below screenshot to see the output for the python program to find the area of a triangle using class.

Python program to find area of a triangle when base and height are given
Now, we will see python program to find the area of a triangle when base and height are given
- In this example, we will ask the user to enter the base and height of a triangle.
- To calculate the area of a triangle we will use the formula Area = (b * h)/2.
- At last,print the area of the triangle to get the output.
Example:
b = float(input('Enter the base of a triangle: ')) h = float(input('Enter the height of a triangle: ')) Area = (b * h)/2 print('The area of the triangle is %0.2f' %Area) You can refer to the below screenshot to see the output for the python program to find the area of a triangle when base and height are given.
