Question

what is the perimeter of the polygon formed by the points P(-4,1) Q(2,4) R(4,0) and S(-2,-3)

Answer 1

Hint, use the distance formula (multiple times), you would probably want to get:

PQ + QR + RS + SP = Perimeter.

Answer 2

okay could u do this problem 4 me btw i put an example up to learn how to do it so no one could just give me the answer i think u showing me would help. @Zelda

Answer 3

Do you know the distance formula?

\[D=\sqrt{(x_2-x_1)^2 + (y_2-y_1)^2}\]

Answer 4

Use that, so say in the start teat the points of P as x1,y1 and for Q as x2,y2 then do that for each of the set of coordinates.

Answer 5

um what did u get for the final answer @Zelda

Answer 6

First tell me what you got for the final answer.

Answer 7

i got 17.5 but i think i messed up

Answer 8

@Zelda
