Apple care coverage for iPad

You can check availability/eligibility for repair - and associated cost for your country/region - here:

iPad Repair & Service - Apple Support

In addition to Apple's mail-in repair service, you can arrange repair at the Genius Bar of your local Apple Store or Apple Authorised Service Provider (AASP):

For practical purposes, in lieu of repairing and returning your own iPad, Apple usually exchange the iPad for a renewed/refurbished iPad of the same model and specification. The cost of the exchange is the same as would otherwise be charged for repair. Unless you have benefit of an active AppleCare plan, an out-of-warranty repair while expensive will be somewhat less than the cost of a replacement iPad.

I think that the date that you've bought it is over so it has been expired as the date has been gone
