The question cannot be answered becasue you have not specified what 12 refers to: the area, perimeter, length of longest side, length of shortest side, difference in lengths, digonal, etc. In any case, even if you had, it would probably not have been possible to answer the question since in most cases there are infinitely many possible answers.
They are all rectangles (or 2 squares and 4 rectangles).They are all rectangles (or 2 squares and 4 rectangles).They are all rectangles (or 2 squares and 4 rectangles).They are all rectangles (or 2 squares and 4 rectangles).
There are infinitely many possible rectangles. Let A be ANY number in the range (0,6] and let B = 12-A. Then a rectangle with width A and length B will have a perimeter of 2*(A+B) = 2*12 = 24 units. Since A is ANY number in the interval (0,6], there are infinitely many possible values for A and so infinitely many answers to the question.
Yes, all Squares are rectangles, but not all rectangles are squares because it needs to have all equal sides.
Yes, all rectangles are parallelograms. However, not all parallelograms are rectangles.

All rectangles are quadrilaterals.
No but all squares are a rectangles
In fact, some are rectangles, but not all are.
A rectangular prism has 12 edges with rectangles and squares for faces
No. Only some parallelograms are rectangles. But all rectangles are parallelograms.
All rectangles are quadrilaterals. A quadrilateral has 4 sides; all rectangles have 4 sides; thus all rectangles are quadrilaterals.
All squares are rectangles also, but not all rectangles are squares, only equilateral rectangles are considered square.
