You have to know latin for this one.
deca is 10
penta is 5
pentadeca is 15
Now add gon for sides or hedron for shape to get
pentadecagon or pentadecahedron
the first is for a 2 dimentional 15 sided shape
the second is a 3 dimentional 15 sided shape
use the appropriate answer for your question.

Hey there!
Use the prefixes:
Un-=1
Dod-=2
Tri-=3
Tetra-=4
Penta-=5
Hexa-=6
Hepta-=7
Octa-=8
Nona-=9
Deca-=10
So 15 is equal to 5+10, which makes a 15-sided polygon as pentadecagon.
Hope it helps!

All the combined terms are Greek.
Penta means five.
Deca means ten.
Gon means shape.
Answer: pentadecagon is the coined word for it.
