Program to calculate the area of the rectangle

Area of a rectangle is the amount of space occupied by the rectangle. A rectangle can be defined as the plain figure with two adjacent sides equal in length. The 4 angles present in the rectangle are also equal. A rectangle can be divided into 4 similar square. The measurement of each interior angle in a rectangle is 90 degrees.

Area of a rectangle is the number of square units takes to fill a rectangle completely.

Algorithm

1. Define the width of the rectangle.
2. Define the Height of the rectangle.
3. Define Area of the rectangle.
4. Calculate the area of the rectangle by multiplying the width and height of the rectangle.
5. Assign the area of the rectangle to the area variable.
6. print the area of the rectangle.

O(1)

C Program

```#include
int main()
{
int width=5;
int height=10;
int area=width*height;
printf("Area of the rectangle=%d",area);
}
```

Output:

```Area of the rectangle=50
```

PHP Program

```<?php
\$width=5;
\$height=10;
\$area=\$width*\$height;
echo "Area of the rectangle=";
echo \$area;
?>
```

Output:

```Area of the rectangle=50
```

Java Program

```public class rectangle{
public static void main(String args[])
{
int width=5;
int height=10;
int area=width*height;
System.out.println("Area of rectangle="+area);
}
}
```

Output:

```Area of rectangle=50
```

C# Program

```using System;
public class Program
{
public static void Main()
{
int width=5;
int height=10;
int area=width*height;
Console.WriteLine("Area of rectangle="+area);
}
}
```

Output:

```Area of rectangle=50
```

Python Program

```width=5
height=10
area=width*height
print("Area of rectangle="+str(area))
```

Output:

```Area of rectangle=50
```
