Titre du sujet: 
Each one of the sides of an equilateral triangle (with a side of 1 u.m.) is divided in three equal parts. The middle segment is replaced by an equilateral triangle and afterwards the original segment is erased. This way, we will obtain a polygon with twelve equal sides. For each side of the new polygon we repeat the mentioned process and thus we obtain what we call an iterative process. In this wy we calculated different numerical aspects such as perimeter, generalized perimeter, area of the obtained polygon.
