What is a rule for finding the number of rectangles of different shape that have a given perimeter?
The number of such rectangles is always infinite.
Select any length, B such that 0 < B ≤ P/2 units of length and let L = P/2 - B.
Then a LxB rectangle has perimeter 2*(L+B) = 2*(P/2 - B + B) = 2*(P/2) = P.
B was chosen arbitrarily from an infinite number of possible values and so there are infinitely many possible solutions.
See discussion section for further thoughts.

What is the perimeter of an area 36cm sqared?
The area doesn't tell you the dimensions or the perimeter. It doesn't even tell you the shape. -- Your area of 36 cm2 could be a circle with a diameter of 6.77 . (Perimeter = 21.27.) -- It could be a square with sides of 6 . (Perimeter = 24.) -- It could be rectangles that measure 1 by 36 (Perimeter = 74) 2 by 18 (Perimeter = 40) 3 by 12 (Perimeter = 30) 4 by 9 (Perimeter = 26). There are an infinite number of more rectangles that it could be, all with the same area but different perimeters.
What is the length and width if the perimeter is 168?
You can't tell the dimensions from the perimeter. There are an infinite number of rectangles, with different dimensions, that all have the same perimeter. If it's 168, then the only thing you can be sure of is that the length and width add up to 84, but you can't tell what either of those dimensions must be.
What is the relationship for perimeter and area for rectangle?
There is no relationship between the perimeter and area of a rectangle. Knowing the perimeter, it's not possible to find the area. If you pick a number for the perimeter, there are an infinite number of rectangles with different areas that all have that perimeter. Knowing the area, it's not possible to find the perimeter. If you pick a number for the area, there are an infinite number of rectangles with different perimeters that all have that area.
