## Way 1 – Area of Triangle Using base and height

In [1]:

```
base = int(input("Please enter base : "))
height = int(input("Please enter height : "))
area = base*height/2
print("Area = ", area)
```

In this approach, we need to have the base and height of the triangle.

Using that base and height, use the formula, i.e. (base*height)/2. And lat last print the area of the triangle.

## Way 2 – Area of Triangle Using three sides

In [1]:

```
side1 = int(input("Please enter side 1 : "))
side2 = int(input("Please enter side 2 : "))
side3 = int(input("Please enter side 3 : "))
s = (side1 + side2 + side3)/2
area = (s*(s-side1)*(s-side2)*(s-side3)) ** 0.5
print("Area = ", area)
```

In this approach, we need all the sides of the triangle, and ask the user to input all the side of the triangle. Once, we know all the sides of a triangle, we will use the Heron’s formula.

Al last, print the area of the triangle.
