Answer:
20.03
Step-by-step explanation:
To find the perimeter of the triangle, we need to find the length of each side, and we can do this finding the distance from each pair of vertix of the triangle:
Knowing that P = (3, -4), A = (-4, 1) and Z = (-2, 3), we have:
side PZ: distance = sqrt((3 - (-2))^2 + (-4 - 3)^2) = 8.6023
side PA: distance = sqrt((3 - (-4))^2 + (-4 - 1)^2) = 8.6023
side AZ: distance = sqrt((-4 - (-2))^2 + (1 - 3)^2) = 2.8284
So the perimeter is PZ + PA + AZ = 8.6023 + 8.6023 + 2.8284 = 20.03
