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. :)
Do rectangles have four congruent sides?
no, if it did then that would be a square
Would Two rectangles that have a same perimeter are congruent?
No
How many rectangles can be drawn with 38 cm as the perimeter?
There would be an infinite number of rectangles possible

Of all rectangles with whole-number dimensions that have givenareahow would you describe the one that has the least perimeter?
dont know dont care
Of all rectangles with whole-number dimensions that gave a given area how would you describe the one that has the greatest perimeter?

Do all rectangles have four cogruent sides?
no rectangles dont have 4 congruent side, otherwise it would be a square or a rhombus.
Do rectangles have four congruent sides?
no, if it did then that would be a square
Would Two rectangles that have a same perimeter are congruent?
No
How many sides dose 4 rectangles have?
Do 4 sides times 4 rectangles. So it would be 4x4=16 sides
How many rectangles in a 4 by 4 square?
To determine the number of rectangles in a 4 by 4 square, we can use the formula for the number of rectangles in an n by m grid, which is (n*(n+1)m(m+1))/4. In this case, n = 4 and m = 4, so the number of rectangles would be (4*(4+1)4(4+1))/4 = 40 rectangles. This includes all possible rectangles of different sizes that can be formed within the 4 by 4 square.
How many rectangles can you build with 8 squares?
Squares are actually also rectangles so you could make 8 rectangles without touching any of the squares. However, if you could cut the squares, that would be a different problem....
