Wait a bit....
You GAVE AWAY the iPad to some other person. So the iPad should have gone away in a completely blank state, with nothing left of your stuff and info. So first you made a full backup on iTunes, thereby preserving all your stuff elsewhere, then after turning off Find My iPad in Settings (thus decoupling the device from your AppleID's monitoring capabilities), you went to Settings / General / Reset and tapped on Erase All Contents and Settings?
That yields a completely blank and unregistered device that the new owner can register and activate to their own AppleID and preserves all your stuff safely. "Restoring" anything means you are loading your info on a device no longer yours.
You can also visit your support profile and delete the device there as well, just for completeness sake: https://supportprofile.apple.com/
