Write Get-RectangleArea so it returns -Width multiplied by -Height.

  - Both parameters are mandatory and typed [double].

  - Both must be greater than zero (use a validation attribute).

  - Width is position 0 and Height is position 1.

    Get-RectangleArea 2 3.5   # 7

'@

    Hints        = @(

        '[Parameter(Mandatory, Position = 0)] goes above the parameter.'

        '[ValidateRange(''Positive'')] rejects 0 and negative numbers (PowerShell 7+).'
