1. You need to actually read the width and height from the console.

2. To print variables, join them together with text using a plus sign.

Purpose: Allows a user to input the height and width of a rectangle and produces the area and perimeter.

using System;

using System.Collections.Generic;

using System.Linq;

using System.Text;

using System.Threading.Tasks;

namespace Ch3Q3

{

class Ch3Q3

{

static void Main(string[] args)

{

double rectHeight;

double rectLength;

Console.WriteLine("Rectangle Area & Perimeter Calculator\n");

Console.WriteLine("Please enter the height of the rectangle: ");

Console.WriteLine("Please enter the width of the rectangle: ");

Console.Read();

Console.WriteLine("The area of the rectangle is: ", rectHeight * rectLength);

Console.WriteLine("The perimeter of the rectangle is: ", (rectHeight * 2) + (rectLength * 2));



Console.ReadKey();

}
