Pat has two sheets of large, square stamps. One sheet consists of 9 stamps arranged in a 3-by-3 square. (That's 3 stamps by 3stamps, not 3 inches by 3 inches.) The other sheet consists of 36 stamps arranged in a 6 by 6 square. The stamps on each sheet are separated by perforated creases. All the stamps on both sheets are the same shape and size.

The total length of the creases on the 3 by-3 sheet is 18 inches.

How many inches of creases does the 6-by-6 sheet have?

assuming sides are not creases: you have to make a 3x3 diagram and split it, and imagine you make it with toothpicks, then remove all the sides.

you will have 12 toothpicks.

you can see where this is going..

you count the toothpicks inside a 6x6

make ratios and solve (i will not do this becuase I AM LAZY!!! also i have to sleep soon)
