There is no lower limit.
Suppose the length is x cm, then perimeter = 12 cm implies that the breadth is 6 - x cm
So the area is x*(6-x) sq cm = 6x - x2 sq cm.
This is a continuous function of x which decreases to zero as x increases towards 6. Although x cannot be 6 since then the rectangle would have no length and therefore would not be a rectangle, it can go infinitesimally close to 6. Then the area is infinitesimally close to 0.

Are some rectangles similar?
no some rectangles cannot be similar. a rectangle is a shape with 2 = sides and then 2 more different = sides. it is impossible because if 2 rectangles were similar than that would not be a rectangle. similar means having corresponding sides no it is not possible
What do you call the group of shapes which has at least one line of symmetry?
You would call the group of shapes which has at least one line of symmetry symmetrical shapes. Stars, circles, and rectangles are considered symmetrical shapes.
Are all rectangles squares if not explain why?
No. All rectangles are not squares. Think of rectangles and squares as boxes. Would you be able to fit a rectangle into the square box? Nope. But you would be able to fit the square into the rectangle box. <---- Hope that helped. :)
Would Two rectangles that have a same perimeter are congruent?
No
Do rectangles have four congruent sides?
no, if it did then that would be a square
