Draw the translation of the figure along the translation vector. My understanding is a translation vector moves without rotation. but the answers I have put in have been wrong. I end up either simplifying my answer or over complicating it.

Set $r$ is a set of rectangles such that (1) only the grid points shown here are used as vertices, (2) all sides are vertical or horizontal and (3) no two rectangles in the set are congruent. if $r$ contains the maximum possible number of rectangles given these conditions, what fraction of the rectangles in set $r$ are squares? express your answer as a common fraction.
