The number of square tiles cannot vary for the floor. Find the HCF (highest common factor) of 150 and 270.

150: 2 x 3 x 5 x 5

270: 2 x 3 x 3 x 3 x 5

15 feet squares will work for both lengths. You then find the number of 15 foot lengths in each side:

10 for 150 and 18 for 270 = 10 x 18 = 180 15 feet squares to cover the entire ice skating rink without any overlap or overhang.
