There are infinitely many possible rectangles.
Suppose A >= 2.25 cm is the length of the rectangle.
and B = 4.5 - A cm is the width.
Then perimeter = 2*(A + B) = 2*(A + 4.5 - A) = 2*4.5 = 9 cm
Also, it is easy to show that A >=B so that A and B cannot swap places.
For each of the infinitely many values of A, you have a rectangle with perimeter 9 cm.

What is the perimeter if the area is 9 sq cm?
Depends on the shape. A square's perimeter would be 4 root 9 ie 12 cm, but you could have a 9 x 1 rectangle which would have a perimeter of 20 cm etc etc
What is The length of a rectangular note pad that is 2 cm longer then twice the width. if the perimeter is 34 cm the what are the length and width?
The length works out as 12 cm and the width works out as 5 cm Check: 2*(12+5) = 34 cm which is the perimeter
What is the perimeter of a 8 cm x 9 cm rectangle?
34cm
What is the width of a rectangular garden with a perimeter of 48 cm and an area of 140 square cm?

What is the perimeter of a square if it has an area of 9 cm?
square must be 3 x 3 so perimeter is 12 cm.
