9 cm is a measurement of length in the metric system, equivalent to 90 millimeters or approximately 3.54 inches. It can be used to describe the size of an object, such as the length of a pencil or the height of a small plant. In various contexts, it might also represent a distance or a dimension in geometry.
The area of a rectangle of sides 9cm and 10cm is:9cm x 10cm = 90cm2This is equivalent to 0.009m2
If you're talking about a five sided figure, just add up your figures.
9cm is longer because 86mm is equal to 8.6cm.
Area is length times width. So... 9x9=81
There is no answer
9cm + 5cm + 9cm + 5cm = 28cm
9cm
Perimeter = 6cm + 6cm + 9cm + 9cm = 30cm
it is 81cm

10mm=1cm therefore 90mm=9cm

9cm is longer because 86mm is equal to 8.6cm.
To find the perimeter of a regular pentagon with 9cm sides, you would multiply the length of one side by the total number of sides. In this case, 9cm x 5 sides = 45cm. Therefore, the perimeter of a regular pentagon with 9cm sides is 45cm.
