can apple tell me where i last used my ipad

If it is turned off then it can't be found electronically, you'll have to ask around and look for it.

Click on the link and read it to find out what to do "If your iPhone, iPad, or iPod touch is lost or stolen" --> https://support.apple.com/HT201472

If your iPad is completely turned off then there is NO technology way to locate it!

Sorry.
