Step 1
The wall is 66 inches high by 72 inches wide.
The tiles are
a) 9   i n 2 = 3   by   3
b) 16   i n 2 = 4   by   4
c) 36   i n 2 = 6   by   6
d) 64   i n 2 = 8   by   8
66 = 6 × 11 = 3 × 2 × 11 72 = 8 × 9 = 2 × 2 × 2 × 3 × 3
Both 66 and 72 have 2 × 3 in common
2 × 3 = 6
Your answer is (c) 36   i n 2
