Question

Calculate the Area and Perimeter for shapes using functions in Python.

Your goal is to match the sample output below:

Welcome to my area and perimeter calculator
======================================================
Circle   : area = 39.82, perimeter = 22.37
Square   : area = 85.19, perimeter = 36.92
Rectangle: area = 41.24, perimeter = 34.24
Triangle : area = 21.16

Here is the code to use for your program (Note you may have to type this code into Trinket directly)

import math

# Add your code here

# TODO -> Add welcome function here

# TODO -> Add circle area function here

# TODO -> Add circle perimeter function here

# TODO -> Add square area function here

# TODO -> Add Square perimeter function here

# TODO -> Add rectangle area function here

# TODO -> Add rectangle perimeter function here

# TODO -> Add triangle area function here

# =====================================================================

# Main Code - DO NOT EDIT ANYTHING BELOW.  Add your functions above

displayWelcome()


radius = 3.56

area = calcAreaCircle(radius)

perimeter = calcPerimeterCircle(radius)

print('Circle   : area = {0:.2f}, perimeter = {1:.2f}'.format(area, perimeter))


side = 9.23

area = calcAreaSquare(side)

perimeter = calcPerimeterSquare(side)

print('Square   : area = {0:.2f}, perimeter = {1:.2f}'.format(area, perimeter))


width = 2.9

height = 14.22

area = calcAreaRect(width, height)

perimeter = calcPerimeterRect(width, height)

print('Rectangle: area = {0:.2f}, perimeter = {1:.2f}'.format(area, perimeter))


base = 7.97

height = 5.31

area = calcAreaTriangle(base, height)

print('Triangle : area = {0:.2f}'.format(area))

Python code:

import math

def displayWelcome():#function to display welcome message

    print("Welcome to my area and perimeter calculator")#prining welcome message

    print("=====================================================")

def calcAreaCircle(radius):#function to calculate area of circle

    return(3.14159265359*radius*radius)#return circle area

def calcPerimeterCircle(radius):#function to calculate perimeter of circle

    return(2*3.14159265359*radius)#return circle perimeter

def calcAreaSquare(side):#function to calculate area of square

    return(side*side)#return square area

def calcPerimeterSquare(side):#function to calculate perimeter of square

    return(4*side)#return square perimeter

def calcAreaRect(width, height):#function to calculate area of rectangle

    return(width*height)#return rectangle area

def calcPerimeterRect(width, height):#function to calculate perimeter of rectangle

    return(2*(width+height))#return rectangle perimeter

def calcAreaTriangle(base, height):#function to calculate area of triangle

    return(0.5*base*height)#return triangle area

displayWelcome()

radius = 3.56

area = calcAreaCircle(radius)

perimeter = calcPerimeterCircle(radius)

print('Circle   : area = {0:.2f}, perimeter = {1:.2f}'.format(area, perimeter))

side = 9.23

area = calcAreaSquare(side)

perimeter = calcPerimeterSquare(side)

print('Square   : area = {0:.2f}, perimeter = {1:.2f}'.format(area, perimeter))

width = 2.9

height = 14.22

area = calcAreaRect(width, height)

perimeter = calcPerimeterRect(width, height)

print('Rectangle: area = {0:.2f}, perimeter = {1:.2f}'.format(area, perimeter))

base = 7.97

height = 5.31

area = calcAreaTriangle(base, height)

print('Triangle : area = {0:.2f}'.format(area))
