Question

create a c++ program with a function named “area” that calculates the area of a rectangle and function named “perimeter”that calculates perimeter of rectangle. Let the user input the data needed for the program.

Answer 1

#include <iostream>
using namespace std;

int area(int length, int width);
int perimeter(int length, int width);

int main()
{
    int length, width;
    cout << "Enter length: ";
    cin >> length;
    cout << "Enter width: ";
    cin >> width;
    cout << "\nArea: " << area(length, width) << "\n";
    cout << "Perimeter: " << perimeter(length, width) << endl;
}

int area(int length, int width) {
    return length * width;
}

int perimeter(int length, int width) {
    return (length + width) * 2;
}
