Equilateral triangles have all sides the same length, and to get the perimeter, you add all the side lengths. 15+15+15=45
I think there are 13 triangles in a 15 sided shape.. Because for convex shapes (Pentagons) You take 2 from how many sides there are in the same. Like 5-2= 3 triangles.. I could be wrong!
The answer is five triangles ?
13 triangles will be formed
