1) just in on side
2) from one end to the other end of the filter

I could see how wide the hole should be but not how long

can someone please help me

Just a hole through the outer layer of black plastic like in the picture. Personally, I put 2 of them side by side myself using a 1/2" drill bit. No need to penetrate the paper element at all.
