Answer 1

#include <iostream>


using namespace std;


const double PI = 3.14;


int main()
{
    cout << "Please select a shape:" << endl;
    cout << "1 - Circle" << endl;
    cout << "2 - Rectangle" << endl;


    cout << endl << "Your choice: ";
    int choice;
    cin >> choice;


    if(choice !=1 && choice !=2)
        cout << "Invalid choice";
    else
    {
        double area;
        if(choice == 1)
        {
            cout << "radius = ";
            double radius;
            cin >> radius;


            area = PI*radius*radius;
        }
        else
        {
            cout << "width = ";
            double width;
            cin >> width;


            cout << "length = ";
            double length;
            cin >> length;


            area = length*width;
        }
        cout << endl << "Area = " << area << endl;
    }
    return 0;
