Explanation
Considering we do have an equilater triangle, all sides are equal in lenght. If the perimeter of the big triangle is 18, then each side is long 6.
Considering that the big one is divided actually into 4 equal smal triangles and M N and P are the midpoints, every side of the small ones is 3.
As such, the perimeter of the inside triangle is 9.
Answer is E
