If it is an LVM partition then "lvextend" command can be used. Check "man lvextend" for details.

Yes -- LVM is great if you don't mind the extra complexity.

I have some windows partition and some /dev/sda ext4 partition.
Ext4 partition is not easy to enlarge size.
So I want to change the partition type to LVM.

The "fdisk -l" output is as follows:

No, that's 'df -h'; you were asked for 'fdisk -l' a COMPLETELY different cmd (although handy to know).
Incidentally, you may need to be root or use sudo to run fdisk.

I must apologize to chrism01 for my mistake.I didn't check carefully.
I have changed my partition to LVM.It is easy to enlarge size.
The "fdisk -l" command output is as follows(now it's LVM partition type):
