Write a Python program using two functions area and perimeter to compute the area and perimeter of a rectangle. The program should take length and breadth of the rectangle as input from the user.

def area(a, b):
    return (a * b)
 
def perimeter(a, b):
    return (2 * (a + b))
 
l = float(input("Enter length: ")) 
b = float(input("Enter breadth: ")) 
print ("Area = ", area(l, b))
print ("Perimeter = ", perimeter(l, b))

Enter length: 9
Enter breadth: 4
Area =  36.0     
Perimeter =  26.0
