Question

Write a parameterized function that calculates and returns the cost per square inch of a rectangular pizza, given its width, height and price as parameters. The formula for area of a rectangle is width * height.

Answer 1

//Solution in C++
#include<iostream>
using namespace std;
double calculateCostperSquare(double width,double height,double price){
        double area=width*height;
        double costperSq=area/price;
        return costperSq;
}
int main(){
        double width,height,price;
        cout<<"Enter Width and Height in inches:";
        cin>>width>>height;
        cout<<"Enter Price:";
        cin>>price;
        double costperSq=calculateCostperSquare(width,height,price);
        cout<<"Cost per Square Inch "<<costperSq<<endl;
}
/*
Output
Enter Width and Height in inches:5 6
Enter Price:12
Cost per Square Inch 2.5

#Solution in Python
def calculateCostperSquare(width,height,price):
    area=width*height
    costperSq=area/price
    return costperSq

print("Enter Width and Height in inches:")
width=(float(input("")))
height=(float(input("")))
print("Enter Price:");
price=(float(input("")))
costperSq=calculateCostperSquare(width,height,price);
print("Cost per Square Inch {} ".format(costperSq))

'''
output
Enter Width and Height in inches:
5
6
Enter Price:
12
Cost per Square Inch 2.5
