For this exercise, you'll use the rectangle class below (you can assume that the length and width are measured in feet).
write a class named carpet that has two data members: size and costpersqfoot. it should have a constructor that takes a rectangle object and a float as parameters and uses them to initialize its data members. it should also have a method named cost that asks the size data member for its area and uses that to calculate and return the cost of the carpet. this is an example of class composition because the carpet class contains a rectangle object as one of its data members.

class rectangle:
"""
represents a geometric rectangle
"""
def , length, width):
self. length = length
self. width = width
def area(self):
return self. length * self. width
def perimeter(self):
return 2 * self. length + 2 * self. width
