Problem:
Rectangle

Write a program which calculates the area and perimeter of a given rectangle.

Input

The length a and breadth b of the rectangle are given in a line separated by a single space.

Output

Print the area and perimeter of the rectangle in a line. The two integers should be separated by a single space.

Constraints

1 ≤ a, b ≤ 100

Sample Input 1

Solution in JAVA (judge verdict: Accepted)

import java.util.Scanner;

public class Main {

	public static void main(String[] args) {
		Rectangle rectangle = null;
		try (Scanner sc = new Scanner(System.in)) {
			int a = sc.nextInt();
			int b = sc.nextInt();
			rectangle = new Rectangle(a, b);
		}
		System.out.println(rectangle.getArea() + " " + rectangle.getEdgeLength());
	}

	static class Rectangle {
		private final int a;
		private final int b;

		Rectangle(int a, int b) {
			this.a = a;
			this.b = b;
		}

		/**
		 * ????????¢?????¢????????????
		 *
		 * @return ??¢???
		 */
		public int getArea() {
			return (a * b);
		}

		/**
		 * ????????¢?????¨?????????????????????
		 *
		 * @return ??¨????????????
		 */
		public int getEdgeLength() {
			return (a * 2 + b * 2);
		}

	}
