Answer 2

If we plot it we see that each side looks to be equal to each other so we can say that this is a square...so to find the perimeter we would choose two points and find the distance between them using the distance formula...

\(\huge{d=\sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2}}}\)

Lets use coords A and B....we would input them into the equation...

\(\huge{d=\sqrt{(1-0)^{2}+(1-(-2))^{2}}}\)

Once you find the distance between them both you would multiply it by 4 to get the perimeter...

Answer 4

AB = √10
BC = √10
CD = √10
DA = √10

I did have √31 for DA.

Answer 5

Oh ok is that what i put as the answer?

Answer 6

You are asked to find the perimeter which is the sum of the lengths of the 4 sides.

I don't know if you are to approximate the perimeter. Look at the question in your text to determine how to leave the answer.

Answer 7

@TylerMckinney16 Did you approximate the perimeter result or go with the exact value?

Answer 8

I went with the exact value.
