always indexed and treated as long term, if cost of acquisition is long term.
you can not calculate separate tax for land and building.
Also, there is a section 54EC in which you can claim exemption , here is a short brief of 54EC:-

such an asset should result in long-term capital gains or profits.
The transfer of the long-term capital asset in question should have taken place post April 1st 2000
The capital gains or profits received by the assessee from the transfer of the long-term capital asset, either
completely or partially, must be invested in the long-term specified asset
