**The Program in C++ to Find the Area and Perimeter of a Rectangle is given below:**

```
#include <iostream>
using namespace std;
int main() {
double length, width, area, perimeter;
cout << "Enter the length of the rectangle: ";
cin >> length;
cout << "Enter the width of the rectangle: ";
cin >> width;
area = length * width;
perimeter = 2 * (length + width);
cout << "Area of the rectangle: " << area << endl;
cout << "Perimeter of the rectangle: " << perimeter << endl;
return 0;
}
```

## Output:

Enter the length of the rectangle: 5

Enter the width of the rectangle: 3

Area of the rectangle: 15

Perimeter of the rectangle: 16

## Pro-Tips**💡**

In this program, the user is prompted to enter the length and width of the rectangle.

These values are then stored in the corresponding variables.

The area of the rectangle is calculated using the formula `area = length * width`

and the perimeter is calculated using the formula `perimeter = 2 * (length + width)`

.

The resulting area and perimeter of the rectangle is then displayed on the screen.
