# Python program to calculate the area of a parallelogram

In this tutorial, we are going to learn how can we calculate the area of the parallelogram in the Python programming language.

The parallelogram is a geometrical figure of a four-sided plane with opposite sides parallel. A parallelogram is a simple object in 2D space that has two parallel sides. The opposite sides and the angles are identical in a parallelogram.

Formula to calculate the parallelogram area:

```Area = base * height
where base is the parallel sides and height is distance between the parallel sides```

Step by step approach to calculating the area is given below:

```define the base of the parallelogram.
define the height of the parallelogram.
calculate the area of the parallelogram using the above formula
The time complexity will be  O(1).```

Now let’s move on our real Python program to do this task:

First of all, let’s take the base as an input from the user:

```#parellel sides of the parallelogram:
Base = float(input('Enter the Base of a parallelogram: '))
```

Now take the height as an input from the user:

```#distance between  two parelle sides
Height = float(input('Enter the Height of a parallelogram: '))
```

After that, let’s calculate the area of the parallelogram using the formula that we learned in mathematics when we were in school:

```# calculate the area of parallelogram
area=Base*Height
```

Now printing the output value using the Python print function to display the result of the calculation:

```print("The area of the parallelogram=",area)
```

Now combine the whole Python program:

```#parellel sides of the parallelogram:
Base = float(input('Enter the Base of a parallelogram: '))
#distance between  two parelle sides
Height = float(input('Enter the Height of a parallelogram: '))
# calculate the area of parallelogram
area=Base*Height
print("The area of the parallelogram=",area)
```

Output:

```Enter the Base of a parallelogram: 6
Enter the Height of a parallelogram: 5
The area of the parallelogram= 30.0```
