An arbitrary large number is the answer for anyrectangle, up to that with a length of 9cm, and 0cm as the width will have a perimeter of 18cm.
Similarly, any rectangle up to that with sides 0cm long, and a width of 9cm will have your 18cm perimeter.
perimeter = 2 (b+h) = 20 there are an infinite number of rectangles that meet the requirement
Infinite amounts.
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.
Rectangles and squares both have 4 corners.
2 triangles and 3 rectangles(:
There would be an infinite number of rectangles possible
Depends what you are drawing on.
There is an infinite number that can have that perimeter
thare is only 1 differint rectangles
perimeter = 2 (b+h) = 20 there are an infinite number of rectangles that meet the requirement
the answer is 12
15
Infinite amounts.
13
I don't understand why there are so many questions about rectangles' perimeter. You just add the length and the width and double your answer....
As many as you want, if they are small enough!
The only one I can think of is a square, where Length=Width=4.
