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.
Answer
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))Output
Enter length: 9
Enter breadth: 4
Area = 36.0
Perimeter = 26.0
