Hello you can use below script.

Add-PsSnapin Microsoft.SharePoint.Powershell –ErrorAction SilentlyContinue
try
{    
#Location of the Backup Folder  
#This will actually initiate the SPSite backup.
Backup-SPSite -Identity "http://portal/sites/production" -Path "C:\SPBackups\production.bak"

#This will actually initiate the SPSite Remove.
Remove-SPSite -Identity "http://portal/sites/production" -GradualDelete
}
