In triangle ABC, AB=BC=5, and CA=6

 Triangle ABC is first rotated clockwise about A for 90 degrees to triangle AB_1C_1

 Triangle AB_1C_1 is then reflected over line B_1C_1 to triangle A_1B_1C_1

 Triangle A_1B_1C_1 is then translated 8 units to the right to triangle A_2B_2C_2

 Triangle A_2B_2C_2 is then dilated about A to triangle A_3B_3C_3 with scale factor -4

What is the perimeter of triangle A_3B_3C_3?
