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.
Formula
A= W x H
where
A is the area of the rectangle
W is the width of the rectangle
H is the height of the rectangle
W is the width of the rectangle
H is the height of the rectangle
Algorithm
- Define the width of the rectangle.
- Define the Height of the rectangle.
- Define Area of the rectangle.
- Calculate the area of the rectangle by multiplying the width and height of the rectangle.
- Assign the area of the rectangle to the area variable.
- print the area of the rectangle.
Complexity
O(1)
Solution C Program
#include <stdio.h>
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
