How to find the area of a triangle on a grid

I honestly forgot how to do a bit of this, and was getting mad at Quora and Google for having nothing helpful since this was due soon. But, this video helped a ton and I managed to get the answer to a question that was stumping me for days

Very Very helpful

I scouted the whole internet and this was the only video I found

Wouldn’t you have to divide by 2 again because it’s part of the formula. Because if you didn’t have to add that triangle you still had to divide it by half.
