Find the Area and Perimeter of Rectangle – Java Program

rectangle is a quadrilateral with four right angles.

Say rectangle is given with side’s length A and B

Area of Rectangle = A * B

Perimeter of rectangle = 2(A+B)

Area and perimeter Of Rectangle


public class AreaOfRectangle {
public static void area(double a, double b){
double area = a * b;
System.out.println("Area of Rectangle: " + area);
public static void perimeter(double a, double b){
double perimeter = 2*(a + b);
System.out.println("Perimeter of Rectangle: " + perimeter);
public static void main(String[] args) {
double a = 3;
double b = 4;
area(a, b);
perimeter(a, b);
