Nine square tiles are laid out on a table so that they make a solid pattern. Each tile must touch at least one other tile along an entire edge. The squares all have sides of length 1. These figures have perimeters of 18 units and 16 units, (a) What are the possible perimeters of the figures that can be formed? (The perimeter is the distance around the figure.) (b) Which figure has the least perimeter? respectively. (a) What are all the possible perimeters of the figures that can be formed? (The perimeter is the distance around the figure.)
