2. Use the diagram below to answer the question that follows.
A diagram showing three patterns of linked polygons. Each pattern consists of a single polygon, followed by two of the same polygon joined along a side, followed by three of the same polygon consecutively joined along sides. The first pattern is labeled 3 gons, and the polygons used are equilateral triangles. The second pattern is labeled 4 gons, and the polygons used are squares. The third pattern is labeled 5 gons, and the polygons used are regular pentagons.
A student arranges regular n-gons, each with a side length measuring 1 unit, as shown in the diagram. The student then calculates the perimeter, P, for each iteration, k, of the given pattern. For any regular n-gon, which of the following equations can be used to calculate the perimeter of the k eth iteration?
- P equals open paren N minus 2 close paren K plus 2
- P equals open paren 2 K plus 2 close paren N
- P equals open paren N minus 1 close paren K plus 1
