4. Create a class called Rectangle that represents a rectangle with width andheight attributes. Include methods to calculate the area and perimeter of therectangle. Create an instance of the class and demonstrate its functionality
Solution
Sure, here is a step by step guide on how to create a class called Rectangle in Python:
Step 1: Define the class and initialize it with width and height attributes.
class Rectangle:
def __init__(self, width, height):
self.width = width
self.height = height
Step 2: Create a method to calculate the area of the rectangle. The area of a rectangle is calculated by multiplying its width by its height.
def area(self):
return self.width * self.height
Step 3: Create a method to calculate the perimeter of the rectangle. The perimeter of a rectangle is calculated by adding twice the width and twice the height.
def perimeter(self):
return 2 * (self.width + self.height)
Step 4: Now, let's create an instance of the Rectangle class and demonstrate its functionality.
# Create a rectangle with width 5 and height 10
rect = Rectangle(5, 10)
# Print the area and perimeter of the rectangle
print("Area: ", rect.area())
print("Perimeter: ", rect.perimeter())
When you run this code, it will print the area and perimeter of the rectangle. The area should be 50 (510) and the perimeter should be 30 (2(5+10)).
