You can use:
sudo apt-get install unrar
or
sudo apt-get install unar
I recommend you install only one of these (unrar in my case). Then use archive manager:
sudo apt-get install file-roller
add a comment
I did install unrar:
sudo apt-get install unrar
then to extract, go to the path of the .rar
file and:
unrar x [filename.rar]
