## Python program to find an area of a rectangle

Let see **python program to find an area of a rectangle**.

- Firstly, we will take input from the user for
**length**and**breadth**using the**input()**function. - Now, we will calculate the area of a rectangle by using the formula
**Area = l * b**. - At last,
**print**the area of a rectangle to see the output.

**Example:**

```
l = float(input('Enter the length of a Rectangle: '))
b = float(input('Enter the breadth of a Rectangle: '))
Area = l * b
print("Area of a Rectangle is: %.2f" %Area)
```

You can refer to the below screenshot to see the output for python program to find an area of a rectangle.

The code we can use to **find an area of a rectangle in Python**.

## Python program to calculate area of a rectangle using function

Here, we will see **python program to calculate the area of a rectangle using function**.

- Firstly, we will
**define a function**with two arguments using def keywords. - Now, we will calculate the area of a rectangle inside the function by using the formula
**Area = width *****height**. - The user will enter the
**width**and**height**of a rectangle and we will pass those values to the function arguments. - At last,
**print**the area of a rectangle to see the output.

**Example:**

```
def AreaofRectangle(width, height):
Area = width * height
print("Area of a Rectangle is: %.2f" %Area)
AreaofRectangle(8, 6)
```

You can refer to the below screenshot to see the output for the python program to calculate the area of a rectangle using function.

The above code, we can use to **calculate area of a rectangle using function in Python**.

## Python program to find area and perimeter of a rectangle

Now, we will see **python program to find area and perimeter of a rectangle**.

- Firstly, we will take input from the user for
**length**and**breadth**using the**input()**function. - Now, we will calculate the
**area**of a rectangle by using the formula**Area = w * h**. - Next, we are calculating the
**perimeter**of a rectangle**Perimeter = 2 * (w + h)** - At last,
**print**the area and perimeter of a rectangle to see the output.

**Example:**

```
w = float(input('Enter the Width of a Rectangle: '))
h = float(input('Enter the Height of a Rectangle: '))
Area = w * h
Perimeter = 2 * (w + h)
print("Area of a Rectangle is: %.2f" %Area)
print("Perimeter of Rectangle is: %.2f" %Perimeter)
```

You can refer to the below screenshot to see the output for the **python program to find area and perimeter of a rectangle.**

The above code, we can use to **find area and perimeter of a rectangle in Python**.

## Python program to find the area and perimeter of a rectangle using function

Let’s see **python program to find the area and perimeter of a rectangle using function**.

- Firstly, we will
**define a function**with two arguments using def keywords. - Now, we will calculate the area of a rectangle inside the function by using the formula
**Area = width *****height**. - Next, we are calculating the
**perimeter**of a rectangle inside the function using the formula**Perimeter = 2 * (width + height)**. - Allow the user to enter the
**width**and**height**of a rectangle by using the**input**function and we will pass those values to the function arguments. - At last,
**print**the area and perimeter of a rectangle to see the output.

**Example:**

```
def Areaofrectangle(width, height):
Area = width * height
Perimeter = 2 * (width + height)
print("Area of a rectangle is: %.2f" %Area)
print("Perimeter of rectangle is: %.2f" %Perimeter)
width = float(input('Enter the width of a rectangle: '))
height = float(input('Enter the height of a rectangle: '))
Areaofrectangle(width, height)
```

You can refer to the below screenshot to see the output for python program to find the area and perimeter of a rectangle using function.

The above Python code we can use to find the area and perimeter of a rectangle using function.

## Python program to find area of a rectangle using classes

Let see **python program to find the area of a rectangle using classes**.

- Firstly, we will create a class called
**rectangle**and the**__init__()**method is used to initialize values of that class. - A method called
**area(self)**return**self.length*self.breadth**which is the area of the class. - The
**user will enter**the value of**length**and**breadth**by using the**input**function. - An
**object**for the class is created as**obj=rectangle(l,b)** - By using the object, the method
**area()**is called with the perimeters as length and breadth taken from the user. - At last,
**print**the area of a rectangle to see the output.

**Example:**

```
class rectangle():
def __init__(self,length,breadth):
self.length=length
self.breadth=breadth
def area(self):
return self.length*self.breadth
l=int(input("Enter length of rectangle: "))
b=int(input("Enter breadth of rectangle: "))
obj=rectangle(l,b)
print("Area of rectangle:",obj.area())
```

You can refer to the below screenshot to see the output for **python program to find the area of a rectangle using classes**.
