What is this called and how do I fix it
Is there a way I can fix the hole? Same on both sides
am I able to just buy a new plate or whatever it’s called? Or should I patch weld it

that plate needs to come off and get patched, and then you need to patch the panel(s) behind the plate

It's called vehicular cancer, and if you have it there (*very common place for it to form), you have it elsewhere, as well. Remove the storage bins from inside the car, remove the sheet metal surrounds, and you'll be seeing daylight, and likely more rust. From there, you can decide how best to handle it. Good luck,

where I drilled out the spot welds. And get a face shield. Safety goggles are nice, but suppose a tiny piece of metal that was on you face, in your hair, finds its way into your eye when you shower? That happened to me in the 70's. To this day, when ever I do metal work, I keep thinking something got into my eyes for the next two days.

tough to say if it is a death trap? better drill out those welds and have a look.
I drove my rx-7 through 4 new jersey winters. And I did the repair 8 years after moving.
that plate was added by mazda to meet DOT crash standards. Mazda left a 1/4 inch metal seam in back that corrosion nests. If your car is going to rust, that's where it will start. The rest of the body was designed well.

sounds like a plan, but you put the metal plate on from the wheel well, not from inside. I'd like to see the place where the trailing arm attaches to the body.
sounds like you are a welder or have access to one?

Here’s my drivers side, all I had time for today. Dosent look too bad was expecting worse. A guy on the face book group said I could keep the plate off and weld a plate over the hole like he did any thoughts on this I just want to make sure I’m doing this right and not putting myself in danger

Brother..... DON'T DRIVE THAT CAR....either fix it or find another shell and swap it.... That is definitely a death trap ....

I do not see any reason why is is not easily saveable. I have seen worse fixed. A plate to replace the removed one and possibly one on the inside and it will be stronger than new.

This post lead me to look into my own vehicle: I have signs of corrosion in the same area, inside the storage bin. I will investigate before putting more miles on the car.
I understand this is a common 1st series problem?
It is in an area which is very easily accessible, it looks like a relatively simple fix.

The issue of rust / corrosion in this area is the same for both SA's and FB's and it is a common area to have problems surface. FB's have storage bins to remove to see to the inside, SA's have larger metal panels that have to be removed to gain access to the same area.
Not sure about it being a "death trap" or not. Probably a matter of some opinion and the extent of the damage. People who don't live in rust prone area's can react more sharply than those who have grown up with the long term effects of salt and chemicals used during the winter.
