Answer:
Hello again! Both D and B are rectangles.
Explanation:
You know that a rectangle has 4 sides like a quadrilateral but it is different. Both of the oppiosite sides are the same length. C would not be one because it is not connected therefore it is not a full shape. Because of A´s even sides, A is not a rectangle. I hope this helps! :]
Sorry I messed up! :]
