You'll need to use iTunes on a computer, to restore the iPad and remove the passcode:

Follow the steps here:

If you forgot the passcode for your iPhone, iPad, or iPod touch, or your device is disabled - Apple Support

Hi

You need to restore ipad using your pc

Turn ipad off

Make sure your pc is running the latest iTunes12.7.2

Connect lead to USB on your pc Press just the power button down on ipad don't let go Connect lead to ipad keep power button pressed down until pc sees ipad Then wait for restore you may need to do this more than once Before it works.
