Example 1-1 (cont'd.)
 Algorithm:
 Get length of the rectangle
 Get width of the rectangle
 Find the perimeter using the following equation:
perimeter = 2 * (length + width)
 Find the area using the following equation:
area = length * width

WAP a C++ Program
parameter = 2 * (length + width)
area = length * width
#include <iostream>
using namespace std;
int main()
{
int length, width, parameter, area; // variables
cout << "Enter length & Width: ";
cin >> length >> width;
parameter = 2 * (length + width);
area = length * width;
cout << "Parameter is :" << parameter << endl;
cout << "Area is :" << area << endl;
return 0;
}
