What are the dimensions of the smallest square that you can make using 18-in. by 24-in. rectangular tiles?
A. 36-in. by 36-in.
B. 144-in. by 144-in.
C. 60-in. by 60-in.
D. 72-in. by 72-in.
This is like finding the LCM for 18 and 24 which would be 72
so the smallest square is 72 by 72
you would need 12 tiles, laid out in 3 rows and 4 columns, each row 24 inches and each column 18 inches
Thanks so much!!! I never understood how to do this, now I do :)
