How can I play my torrent file?

This is really frustrating! I'm a newbie at torrent, and im just 12, so i dont really understand the stuff much, but i really want to play the sims, and my dad doesnt want to waste money, so i decided to get it by torrent.
The file is called The sims 3 - Pets (Fixed).rar. I got it from torrent and when it finished the downloading, it said seeding, so i waited an hour and then clicked the stop button. It says it's Finished, and then a new file appeared called The sims 3 - Pets (Fixed).rar , so i extracted it,then I got lots of files under the The sims 3 - Pets (Fixed).rar files on my desktop now, but what do i do with them?

Please help! This is the first time i've tried so hard for a game, and i really want to play it.

EDIT: oh, in one of these many files theres a file that says Sims3EP05Setup, so i clicked on it and the error said "This product requires an installment on the sims 3." something like that.

 

im going to break this to you as gently as i can as i have kids.what you are doing is piracy and cannot be talked about on this site as per forumn rules.the mods are most likely going to close this thread.

 

Oh so i just have to buy it? sorry about this

 

Alright sorry i didnt know i thought it was legal sorry
