Increate xfs partition size lvm

I am trying to increase xfs disk lvm but I am missing something

"/" size is 70 GB and I want to enlarge it to 90GB .
I enlarged the underlying /dev/sda size to 140gb (it was 120gb) So I have enough space to add. 
Also - vgdisplay lvdisplay shows nothing.
Any idea ?

lsblk

Try this.

1. lvextend -L +90G /dev/mapper/rhel_dent--sasacprd01-root
2. xfs_growfs /dev/mapper/rhel_dent--sasacprd01-root
