This is supposed to be a test, please answer the questions by yourself. OpenStudy is where you are supposed to LEARN, and not a place where you get free answers.

For this question, I suggest you to draw the triangle out on a quad paper and patiently think about how you can solve it.Perimeter is equal to the sum of all the lengths.

For instance, |dw:1401224280569:dw| The perimeter of this triangle is a+b+c.

I would draw the triangle on a graph with the points and count the boxes. That's what I've always done and it seems to work unless the teacher has added a unit of measurement. Which in your case it looks like they haven't so my plan might work out. If anyone smarter comes along with a more logical answer listen to them instead of me! My way is kind of the cheater way and we want you to learn! :D
