Question

Nine square tiles are laid out on a table so that they make a solid pattern. perimeters of the fiques that you can be formed?

Answer 1

Let the side of one square be x.
The maximum perimeter will be when the squares will be lined end to end.
This will be:
x + 9x + 9x + x
= 20x

The perimeter of the figures formed will be less than or equal to 20x.
