The perimeter is the sum of the lengths of the three sides.
To find the perimeter, you need to find the lengths of the three sides.
For each side, you are given the points at the two ends.You need to find the distance between those two points.
Once you have all thee distances, add them up.
That's how.
subtract the midpoint numbers from endpoint b
x coordinate: 3- -1 = 4
y coordinate: -5 -2 =-7
now subtract the x number from the midpoint and add the y number to the midpoint
-1 -4 = -5
2- - 7 =9
missing endpoint is (-5,9)
