Question

Write a java program To find Area and perimeter of a rectangle(Area=l*b Perimeter=2(l+b))

Answer 1

Answer:

import java.util.Scanner;

public class Rectangle {

   public static void main(String[] args) {

       

       float length, width, area, perimeter;

       // Create scanner class object

       Scanner in = new Scanner(System.in);

       // Input length and width of rectangle

       System.out.print("Enter length of rectangle: ");

       length = in.nextFloat();

       

       System.out.print("Enter width of rectangle: ");

       width  = in.nextFloat();

       

       // Calculate perimeter  of rectangle

       perimeter = 2 * (length + width);

       // Calculate area of rectangle  

       area = length * width;

       

       // Print perimeter and area of rectangle

       System.out.println("Perimeter of rectangle is " + perimeter + " units.");

       System.out.println("Area of rectangle is " + area + " sq. units.");

   }

}
