Problem statement
Define a class named Rectangle. The constructor takes two numeric parameters: width and height, and must store them as instance attributes self.width and self.height. Implement an instance method area(self) that returns the product of the instance's width and height (self.width * self.height).
Task
Implement a Rectangle class with width and height instance attributes and an area() method that uses self to compute area.
Examples
Input format
Construct a Rectangle with Rectangle(width, height) and call .area().
Output format
Return the numeric area value from the area() method.
Constraints
width and height will be numbers (integers or floats).
Samples
Sample 1
Input
Rectangle(2.5, 4).area()
