Pentagon has 5 sides Regular => each side 9cm => perimeter = 5 x 9cm = 45cm
the perimeter or the circumference
Any plane shape.
Assuming no fractional dimensions, least possible area would be a rectangle measuring 1cm x 9cm. Area increases to a maximum of 25 sq cm when shape is square, ie 5cm x 5cm.
Any shape you want. "Perimeter" is not some esoteric function, it is merely the total measurement of the sides of the figure.
Perimeter = 6cm + 6cm + 9cm + 9cm = 30cm
it is 81cm
Well, honey, making a shape with a perimeter of 9cm is as easy as pie. You could have a triangle with sides measuring 3cm, 3cm, and 3cm. Or you could have a rectangle with sides measuring 2cm and 2.5cm. Just remember, the perimeter is the sum of all the sides, so get those measuring tapes out and get creative!
9cm + 5cm + 9cm + 5cm = 28cm

31 centimeters
If you're talking about a five sided figure, just add up your figures.
Any plane shape. Take a piece of string and tie it into a loop of length 9 cm. Put in down on a flat surface. Then move bits of the loop in and out - every one of the shapes you make will have a perimeter of 9 cm.
The perimeter would be 8 + 9 + 10 = 27cm
28 cm
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.
To draw a shape with a 9cm perimeter, you can create a triangle, square, or rectangle. For a triangle, you could have sides measuring 3cm, 3cm, and 3cm. For a square, all four sides would be 2.25cm. For a rectangle, two sides could be 2cm and the other two sides could be 2.5cm. These shapes will all have a perimeter of 9cm.
