Answer:
36
Step-by-step explanation:
From the diagram, the following is true;
AY = YB = 7
BZ = ZC = 6
XC = XA = 5
perimeter of the triangle is the sum of all the sides
Hence ;
Perimeter = AY+YB+BZ+ZC+XC+XA
Perimeter of the triangle = 7+7+6+6+5+5
Perimeter of the triangle = 36
hence the perimeter of the triangle is 36
