Answer 2

Answer:

Example

Input

Length of rectangle = 30

Width of rectangle = 20

Output

Perimeter of rectangle is 100.0 units.

Area of rectangle is 600.0 sq. units.

Step by step

Input length and width of rectangle from user. Store it in some variable say length and width.

Apply formula to calculate rectangle perimeter i.e.perimeter = 2 * (length + width).

Apply formula to calculate rectangle area i.e.area = length * width.

Finally, print the value of perimeter and area.

/**

* Java program to find perimeter and area of a rectangle.

*/

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.");

}

Output

Enter length of rectangle: 30

Enter width of rectangle: 20

Perimeter of rectangle is 100.0 units.

Area of rectangle is 600.0 sq. units.
