### Examples

```csharp
using System;
using Aspose.Cells;

namespace AsposeCellsExamples
{
    public class ValidationMethodRemoveAreaWithCellAreaDemo
    {
        public static void Run()
        {
            // Create a workbook
            Workbook workbook = new Workbook();
            Worksheet worksheet = workbook.Worksheets[0];

            // Add a validation to the worksheet
            Validation validation = worksheet.Validations[worksheet.Validations.Add()];
            validation.Type = ValidationType.WholeNumber;
            validation.Operator = OperatorType.Between;
            validation.Formula1 = "10";
            validation.Formula2 = "100";

            // Add initial validation area
            CellArea initialArea = CellArea.CreateCellArea(0, 0, 0, 0);
            validation.AddArea(initialArea);

            // Add another area to the validation
            CellArea additionalArea = CellArea.CreateCellArea(1, 1, 1, 1);
            validation.AddArea(additionalArea);

            Console.WriteLine("Validation areas count after adding: " + validation.Areas.Length);

            // Remove the additional area
            validation.RemoveArea(additionalArea);

            Console.WriteLine("Validation areas count after removing: " + validation.Areas.Length);

            // Add multiple areas
            CellArea[] multipleAreas = new CellArea[]
            {
                CellArea.CreateCellArea(2, 2, 2, 2),
                CellArea.CreateCellArea(3, 3, 3, 3),
                CellArea.CreateCellArea(4, 4, 4, 4)
            };
            validation.AddAreas(multipleAreas, false, false);

            Console.WriteLine("Validation areas count after adding multiple: " + validation.Areas.Length);

            // Remove one of the areas
            validation.RemoveArea(multipleAreas[1]);

            Console.WriteLine("Validation areas count after removing one: " + validation.Areas.Length);
        }
