Answer:
37.5
Step-by-step explanation:
the triangle is enlarged by a factor of 2.5 so you multiply all of the numbers in XYZ by 2.5 then add them
15+10+12.5=37.5 units
you can find the scale factor by diving 15 by 6. the scale factor is 2.5. u can multiply all the values of the first triangle by 2.5, and add them together to find the perimeter of the larger triangle.
