What are the dimensions of the smallest square that you can make using 18-in. by 24-in. rectangular tiles?

Question

A. 36-in. by 36-in.

B. 144-in. by 144-in.

C. 60-in. by 60-in.

D. 72-in. by 72-in.

Answer 1

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

Answer 2
