8 sides on an octagon. 1 cmis equal to10mm. Therefor, 10 x 8= 80 mm
If it's a regular octagon, the perimeter is 8 times the length of one side.
The perimeter is 72.
Perimeter = 8*15 = 120 cm
Approximately 6,789.98 units2
Just add together its 8 sides
If it's a regular octagon, the perimeter is 8 times the length of one side.
Its perimeter is: 8*6 = 48 cm
The perimeter of a octagon is the sum of all its sides.
Multiply the length of one side (7 cm) by the number of side (8) to see that the perimeter is 56 cm. This works because a regular octagon has 8 sides of equal length..
The perimeter is 56.
It is the sum of the lengths of the octagon's eight sides.
The perimeter of an octagon is 64 only if it is a regular octagon and the length of one side is 8. An irregular octagon may or may not have a perimeter of 64 (whatever units of measure you choose to use) depending on what the lengths of the individual sides are.
The perimeter of an octagon that has one side of 2 inches is 16 inches.
perimeter of octagon is 128 cm= 8 * side side of the octagon=128/8=16 cm
Divide the perimeter by eight.
There is no formula for an octagon. There are formulas for figuring out different aspects of an octagon, such as its perimeter, diameter, etc.
An octagon is any 8-sided 2-dimensional figure. It can be any size, so it can have any number of millimeters.
