Finally, I can conclude that everywhere, not only in Cajamarca, are a lot of polygonal figures and they are important because many things we use now a days, tablets, cellphones, boards, books, etc. have a shape thanks to plygons. Also, knowing area and perimeter help us a lot, spesifically in the area of architecture, the same as the scale, that help architectures kwon where things must be in a small graph of it.
