Good morning from Canada! :D
What we know:
-there are 2.54cm per inch
-there is 1 yard
-1 yard=36 inches
Basically, this question is asking us to make simple conversions from centimeters to inches, based on how many centimeters there are in a yard.
All we need to do to find the number of centimeters is to multiply 36 (the number of inches per year) by 2.54 (the number of centimeters in an inch).
36×2.54=91.44cm
Therefore there are 91.44cm in 1 yard.
Hope this helps!
