Answer:
108
Step-by-step explanation:
divide 9 by 2, you get 4.5. multiply that by 24 and you get your answer.
Perimeter = side 1 + side 2 ´+ side 3.
Triangle 1
Perimeter = 6 + 8 + 10
= 24
Triangle 2
Perimeter = 9 + 12 + 15
= 36
Ratio
24/36 = 2/3
The ratio of the perimeters is also 2/3
Answer:

4(3) - 15
12 - 15
= -3
