Problem
A 
x
rectangle is covered without overlap by 3 shapes of tiles: 
x, 
x
, and x, shown below. What is the minimum possible number of x tiles used?
(A) (B) (C) (D) (E) 
Solution 1
We can eliminate B, C, and D, because they are not 
any multiple of . Finally, we see that there is no way to have A, so the solution is 
.
