C#: Calculate the of each city's size in square from the given area of some cities in the United States

C# Sharp Math: Exercise-6 with Solution

The square root of the area of a square represents the length of any side of the square.

Write a C# Sharp program to calculate each city's square area based on the given area of some cities in the United States.

Sample Solution:

C# Sharp Code:

using System;
using System.Text;
namespace exercises {
  class Program {
    public static void Main() {
      // Create an array containing the area of some squares.
      Tuple < string, double > [] areas = {
        Tuple.Create("Sitka, Alaska", 2870.3),
        Tuple.Create("New York City", 302.6),
        Tuple.Create("Los Angeles", 468.7),
        Tuple.Create("Detroit", 138.8),
        Tuple.Create("Chicago", 227.1),
        Tuple.Create("San Diego", 325.2)
      };

      Console.WriteLine("{0,-18} {1,14:N1} {2,30}\n", "City", "Area (mi.)",
        "Equivalent to a square with:");

      foreach(var area in areas)
      Console.WriteLine("{0,-18} {1,14:N1} {2,14:N2} miles per side",
        area.Item1, area.Item2, Math.Round(Math.Sqrt(area.Item2), 2));
    }
  }
}

Sample Output:

City                   Area (mi.)   Equivalent to a square with:

Sitka, Alaska             2,870.3          53.58 miles per side
New York City               302.6          17.40 miles per side
Los Angeles                 468.7          21.65 miles per side
Detroit                     138.8          11.78 miles per side
Chicago                     227.1          15.07 miles per side
San Diego                   325.2          18.03 miles per side
