Write a program that calculates and displays the area of a rectangle.
Solution
The area of a rectangle can be calculated using the following formula:
Area = Base × Height
In this exercise, the user enters values for Base and Height and the program (or script) calculates and displays the area of the rectangle. The solution to this problem is shown here.
PHP
<?php
echo "Enter the length of Base: ";
$base_parallelogram = trim(fgets(STDIN));
echo "Enter the length of Height: ";
$height_parallelogram = trim(fgets(STDIN));
$area = $base_parallelogram * $height_parallelogram;
echo "The area of the parallelogram is ", $area;
?>
Java
public static void main(String[] args) throws java.io.IOException {
java.io.BufferedReader cin = new java.io.
BufferedReader(new java.io.InputStreamReader(System.in));
double area, base_parallelogram, height_parallelogram;
System.out.print("Enter the length of Base: ");
base_parallelogram = Double.parseDouble(cin.readLine());
System.out.print("Enter the length of Height: ");
height_parallelogram = Double.parseDouble(cin.readLine());
area = base_parallelogram * height_parallelogram;
System.out.println("The area of the parallelogram is " + area);
}
C++
#include <iostream>

cout << "Enter the length of Base: ";
cin >> base_parallelogram;
cout << "Enter the length of Height: ";
cin >> height_parallelogram;
area = base_parallelogram * height_parallelogram;
cout << "The area of the parallelogram is " << area;
return 0;
}
C#
static void Main() {
double area, base_parallelogram, height_parallelogram;
Console.Write("Enter the length of Base: ");
base_parallelogram = Double.Parse(Console.ReadLine());
Console.Write("Enter the length of Height: ");
height_parallelogram = Double.Parse(Console.ReadLine());
area = base_parallelogram * height_parallelogram;
Console.Write("The area of the parallelogram is " + area);
Console.ReadKey();
}
Visual Basic
Sub Main()
Dim area, base_parallelogram, height_parallelogram As Double
Console.Write("Enter the length of Base: ")
base_parallelogram = Console.ReadLine()
Console.Write("Enter the length of Height: ")
height_parallelogram = Console.ReadLine()
area = base_parallelogram * height_parallelogram
Console.Write("The area of the parallelogram is " & area)
Console.ReadKey()
End Sub
Python
base_parallelogram = float(input("Enter the length of Base: "))
height_parallelogram = float(input("Enter the length of Height: "))
area = base_parallelogram* height_parallelogram
print("The area of the parallelogram is", area)
