## Area of Rectangle

To find the area of a rectangle whose length and breadth are given, use the following formula.

`Area of Rectangle = length * breadth`

## Program

In the following program, we shall define a function `areaOfRectangle()`

that takes length and breadth as arguments and return the area of rectangle.

We read length and breadth as integers from user, call `areaOfRectangle()`

with the length and breadth passed as arguments. You can also read length and breadth as floating-point numbers from user using float() function. In the following program we use int() and you may try float() as practice.

**Input**

`length`

, `breadth`

of rectangle, where `length > 0`

and `breadth > 0`

.

**Python Program**

```
def areaOfRectangle(length, breadth) :
if length < 0 or breadth < 0:
print('Length or breadth cannot be negative.')
return
return length * breadth
length = int(input('Enter length : '))
breadth = int(input('Enter breadth : '))
area = areaOfRectangle(length, breadth)
print(f'Area of Rectangle : {area}')
```

**Output**

```
Enter length : 5
Enter breadth : 8
Area of Rectangle : 40
```

**Important Points regarding above program**

- input() function reads a string from standard input. Therefore, we have used int() function to convert string to integer.
- If given length or breadth is less than zero, we are returning nothing.
