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

3 5

Sample Output 1

15 16

Solution in C# (judge verdict: Accepted)

using System;

namespace Rectangle
{
	class Rectangle
	{
		private int height;
		private int weight;

		public Rectangle()
		{
			height = 0;
			weight = 0;
		}

		public void getHeightAndWeight()
		{
			string s = Console.ReadLine();
			string[] sArray = s.Split(' ');

			height = int.Parse(sArray[0]);
			weight = int.Parse(sArray[1]);
		}

		public int Height
		{
			set { height = value; }
			get { return height; }
		}

		public int Weight
		{
			set { weight = value; }
			get { return weight; }
		}

	}

	public class MainClass
	{
		public static void Main(string[] args)
		{
			int area = 0, periphery = 0;

			Rectangle rec = new Rectangle();

			rec.getHeightAndWeight();

			area = rec.Height * rec.Weight;
			periphery = rec.Height * 2 + rec.Weight * 2;

			Console.WriteLine("{0} {1}", area, periphery);
		}
	}
