Answer:
um I did the math and I got 5, so i dont really understand
B hope it helps have a good day
If you plot the points you will find you have to use the distance formula. Pick out 2 pairs label them (x1,y1) (x2,y2) then plug it into the distance formula. The repeat for the other sides. So you should get (2,5) (4,3) plug into distance formula what is get it distance between those two points, then (4,3) (-2,-1) plug into distance formula to get an answer, lastly (-2,-1) (2,5) plug in. Now you have three answers add all together and here is your perimeter of a triangle.
122/11....u divide 122 by 11...or how many times does 11 go into 122.
122/11 = 11.09 with a line over the 09 because it is repeating
