Eight 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.

Here is an example: The figures have a perimeter of 14 and 16 respectively.

(a) Find different arrangements of these eight tiles to see what other perimeters you can find.

List the possible perimeters.

(b) Draw or describe the arrangement that has the smallest perimeter?

(c) Draw or describe the arrangement that has the largest perimeter?
