Answer:

  45 cm

Step-by-step explanation:

2 lines will divide the square in thirds. 2 additional lines will divide those thirds into ninths. Pat's 4 lines total 18 cm.

To divide the square into sixths requires 5 lines. To divide it into 36ths requires 5 additional lines. Hence the total number of lines on the second paper is 10/4 = 5/2 times the total on the first paper.

The total length of lines on the second paper is ...

  (5/2)(18 cm) = 45 cm
