Total perimeter of the two triangles is 6*3+6*3 = 36
Now, we know the perimeter of the small intersecting triangle to be 9.
So, all we have to do is subtract sum of SWV from PQR and STU
36 - 9 = 27
(Think of it like this: SVW is now not included in the sum any longer)
WS+SV+WV are not the part of the perimeter anymore
