## __Write a Python program to print area of rectangle using function & return its value to main function__

Given length and width of the rectangle , write a Python program to print area of rectangle using function & return its value to main function .

### Sample input

4

3

Sample output

The area of the rectangle is: 12

__Write a Python program to print area of rectangle using function & return its value to main function__

The objective of the code is to find the area of the rectangle and return it to the main function that is driver function of the code .

__Algorithm:__

__Algorithm:__

- Start the program.
- Define the
`area()`

function with two arguments`length`

and`width`

. - Inside the
`area()`

function, multiply the length and width of the rectangle and return the product as the area of the rectangle. - In the main program, ask the user to input the length and width of the rectangle using
`input()`

function and store them in variables`l`

and`w`

. - Call the
`area()`

function with arguments`l`

and`w`

and store the returned value in a variable`a`

. - Print the area of the rectangle using
`print()`

function. - End the program.

__Code(Python):-__

__Code(Python):-__

### def area(length, width): return length * width

if __name__ == '__main__': l = int(input("Enter length of rectangle: ")) w = int(input("Enter width of rectangle: ")) a = area(l, w) print(f"The area of the rectangle is: {a}")

__Output:__

__Output:__

### Enter length of rectangle: 4Enter width of rectangle: 3The area of the rectangle is: 12

__Explanation__

__Explanation__

In this program, the `area()`

function takes two arguments `length`

and `width`

and returns their product as the area of the rectangle. The main program asks the user to input the length and width of the rectangle using `input()`

function and stores them in variables `l`

and `w`

. It then calls the `area()`

function with arguments `l`

and `w`

and stores the returned value in a variable `a`

. Finally, it prints the area of the rectangle using `print()`

function.
