Answer:
18 kilometers
Step-by-step explanation:
If each 1 cm represents 9 kilometers.
How many would 2 cm represent?

Because It Can Be Simplified Many Ways
132/2 = 66
66/2 = 33
33/3 = 11
11/11 = 1
132 = 2^2 * 3 * 11
55121/11 = 5011
5011/5011 = 1
55,121 = 11 * 5011
LCM = common factor with larger exponent * not common factors
LCM = 2^2 * 3 * 11 * 5011
LCM = 661,452
I don’t know how to solve those type of problems sorry
