Write classes Rectangle and Triangle both having a method area(). Now write a function that can take any shape and print the area of that shape, demonstrating polymorphism.
Example 1:
Input: Rectangle with length 5 and breadth 4 Output: "Area: 20"
Example 2:
Input: Triangle with base 5 and height 4 Output: "Area: 10"
Override the area() method in each subclass to calculate the area of the shape. Write a function that takes an instance of a shape and calls its area() method.
class Rectangle:
def __init__(self, length, breadth):
self.length = length
self.breadth = breadth
def area(self):
return self.length * self.breadth
class Triangle:
def __init__(self, base, height):
self.base = base
self.height = height
def area(self):
return 0.5 * self.base * self.height
def print_area(shape):
print(f"Area: {shape.area()}")
# Test the function
rectangle = Rectangle(5, 4)
print_area(rectangle) # Output: Area: 20
triangle = Triangle(5, 4)
print_area(triangle) # Output: Area: 10
