Get Size and Position of a given Border?

So, I have a custom UUserWidget and I would like to create a function that retrieves a border reference and gets the size and location typed into that border’s details.
I checked Border.h and there doesn’t seem to be any Size or Location property. Are those variables inherited from a parent class or something?

I’m kinda lost as to how to do it to be honest, so I’d appreciate any advice on this.
Thanks in advance.
