Help with cutting an object

Hello everyone,

I am a new user of SketchUp, and I am having trouble with cutting an item. If you could suggest a tutorial or tell me how to do it, I would greatly appreciate it. I would like to make those triangular cuts or even simply cut the part that is marked in red, so that I can create a rectangle (something like a door in the wall).

Thanks in advance,
