Answer:
9th Triangle
Step-by-step explanation:
Given the area of four triangles:
If the Scale factor is 1.5.
This is a geometric sequence and the common ratio is 1.5 X 1.5.
Therefore, the area of any n triangle can be determined using the function:

We want to determine which triangle has an area greater than
.
When A(n)=15000

Therefore, the 9th triangle has an area greater than
.
For 4 you just need to multiply the 7 and 33 together and add 32. Then put your awnser over 33. (if it is asking for the fraction)
24
It goes into 24 once and into 48 twice
