WHAT IS THE LARGEST PERIMETER THAT CAN BE CREATED FOR AN ARRAY CREATED FROM 24 ONE INCH TILES.

Try laying them in a line...

no

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? 
12 + 12 + 12 + 12 + 1 + 1

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.
