Laying the tiles in a line gives you a perimeter of 50 inches.

24 + 24 + 1 + 1

Can you arrange the tiles in any other way to give you a larger perimeter?

Print this graph paper and draw your 24 tiles on it.

Remember that each tile measures 1 inch on each side.

The perimeter is the distance around the figure.
