10. Class Named Rectangle to Compute Area

Write a Python class named Rectangle constructed from length and width and a method that will compute the area of a rectangle.

Python: Area of a rectangle

In Euclidean plane geometry, a rectangle is a quadrilateral with four right angles. To find the area of a rectangle, multiply the length by the width.
A rectangle with four sides of equal length is a square.
Following image represents the area of a rectangle.

Sample Solution:

Python Code:

class Rectangle():
    def __init__(self, l, w):
        self.length = l
        self.width  = w

    def rectangle_area(self):
        return self.length*self.width

newRectangle = Rectangle(12, 10)
print(newRectangle.rectangle_area())

Sample Output:

120
