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.

Infinite amounts.

As many as you want, if they are small enough!

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....
