Answer:
Yes. In a rectangle of 2 row squares of √11 legs. We still have four right angles and two pair of parallel sides.
Explanation:
To make a rectangle out of a 2 rows of 11 u² square, is to draw 2 squares with √11 legs. Joining them we can clearly see a new rectangle with (2√11) height and √11 width. Four right angles, two parallel legs. Exactly what makes a rectangle.
