Answer:
Your answer is "A".
Explanation:
Basically, your question is asking for the side lengths after the transformation. However, the transformation it would undergo does not change the size of the rectangle, it only changes its position on the graph. This means, all you need to do is count the number of squares from one point to another.
From point A to B, there are 3 squares. From point B to C, there are 5 squares. Therefore, your answer is A.
