#Sept 4 Lab Practice Part 2 Problem 1
#Write a Python program that calculates the perimeter and area of the 
#rectangle, and the area of the circle. Ask user to enter length and width 
#of rectangle, and ask user to enter radius of the circle.
#Use the following formulas:
#area = width * length 
#perimeter= 2*length + 2*width 
#areaCircle = 3.14 * radius * radius 

#input
width=float(input("enter width "))
length=float(input("enter length "))
radius=float(input("enter radius "))


#calculations
area = width * length
perimeter= 2*length + 2*width
areaCircle = 3.14 * radius * radius

#output
print("area of rectangle is",area)
print("perimeter is",perimeter)
print("area of the circle",areaCircle)
