Write an object oriented program to find the area and perimeter of rectangle .

To calculate the perimeter and area of rectangle​, we need the dimensions of two adjacent sides(length and width) of a rectangle. The area of a rectangle​ is the amount of two-dimensional space inside the boundary on rectangle. The perimeter of a rectangle​ is the linear distance around the boundary of the rectangle.

Java program to calculate area and perimeter of a rectangle

package com.tcc.java.programs;

import java.util.*;

public class RectangleAreaPerimeter {

public static void main(String args[]) {

int length, width, area, perimeter;

Scanner in = new Scanner(System.in);

System.out.printIn("Enter length of Rectangle");

length = in.nextInt();

System.out.printIn("Enter width of Rectangle");

width = in.nextInt();

// Area of rectangle = length X width

area = length*width;

// Perimeter of rectangle = 2 X (length X width)

perimeter = 2*(length + width);

System.out.printIn("Area of Rectangle : "+ area);

System.out.printIn("Rectangle of Rectangle : "+ perimeter);

}

}

Output:

Enter length of Rectangle

4

Enter width of Rectangle

5

Area of Rectangle : 20

Rectangle of Rectangle : 18
