Final answer:

To find the perimeter of a pentagon with the given vertices, you need to calculate the distance between each pair of consecutive vertices and then add them up.

Step-by-step explanation:

To find the perimeter of a pentagon with the given vertices, you need to calculate the distance between each pair of consecutive vertices and then add them up.

Using the distance formula d = sqrt((x2-x1)^2 + (y2-y1)^2), where (x1, y1) and (x2, y2) are the coordinates of two points, you can find the distances between the vertices:

  1. d(t, r) = sqrt((4-4)^2 + (-2-3)^2)
  2. d(r, i) = sqrt((4-(-1))^2 + (-2-(-2))^2)
  3. d(i, a) = sqrt((-1-2)^2 + (-2-(-6))^2)
  4. d(a, l) = sqrt((2-(-1))^2 + (-6-3)^2)
  5. d(l, t) = sqrt((-1-4)^2 + (3-3)^2)

Finally, you add up the distances to get the perimeter of the pentagon.
