any 2-D shape could have a perimeter of 9cm. One example is a square with sides of 9/4 cm.

Pentagon has 5 sides Regular => each side 9cm => perimeter = 5 x 9cm = 45cm
the perimeter or the circumference
Any plane shape.
Any shape you want. "Perimeter" is not some esoteric function, it is merely the total measurement of the sides of the figure.
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.
Perimeter = 6cm + 6cm + 9cm + 9cm = 30cm
it is 81cm
you cant do that becaues to get a perrimetr you need to add all the sides. when you do that it wll either be less then 9 or more then 9 in conclusion you cant get a shape that has a perimeter of
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.
18.5cmImproved Answer:-Perimeter = 9+9.5+9+9.5 = 37cm
