Pat starts with two identical square pieces of paper. On the first one, she draws straight lines that divide the paper into a 3-by-3 grid of squares. The total length of the lines she draws is 18 cm.

On the second piece of paper, Pat draws straight lines that divide the paper into a 6-by-6 grid of squares.

What is the total length of the lines that Pat draws on the second piece of paper?

Well from the other post we know she draws 4 lines.     18cm/4 lines = 4.5 cm per line

  also the paper is.  4.5 cm x 4.5 cm.   
now can you do the 6 x 6. One?    Hint:  it takes 5 lines to divide into 6 spaces....

You can try drawing a 3 by 3 grid and a 6 by 6 grid. Try counting the lines you drew
