As you can see, i put rook there to prepare to mate, but it says blunder, i know ra8 is good because it gives free rook but ism't mate better? (the orange arrow is what i moved next)
How is this a blunder?

I don’t know how that is a blunder. Maybe chess.com can see into the future or something.

Ra8 is best because it wins the rook, rc1 and your opponent plays Rb8 and it defends check mate and also you don't win the rook

The given position in the board is after White has completed his move.
It's Black to move after 36. Rc1.

The issue is, like SB has noted, 36. Rc1 Rb8 37. Rcc7 o-o (or even 36. Rc1 o-o directly) and you also have Black's passed pawn to worry about. I'm assuming that Black can still castle in that position (without looking at the actual game).
Remember that after 36. Rc1 it would be your opponent's turn! Hoping for a checkmate with 37. Rc8 is only a virtual imagination on our part.
When you play a move that has a potential to checkmate your opponent next turn but it can be easily parried, then it could well be classified as a blunder, especially when there are winning alternatives available. This is in contrast to an unstoppable attack where it would be classified as a win or even a checkmate in several moves.
EDIT: Went into the source game and found that Black had moved the king on move #11, so castling would not be possible.
oh thanks, i see. it opponent played ra8 then he defends mate and missed opportunity to win the rook, i think its better to play it safe when there's already a good move
