920 mm. Because since an octagon has 8 sides and they are all 115 in length, to find the total perimeter simply add up 115 8 times, or multiply 115 by 8.
480mm (60mm x 8 sides = 480)
An octagon is an eight-sided figure. If a regular octagon has a perimeter of 24 inches, then each side will be 24 / 8 = 3 inches.
Assuming that the perimeter of the regular octagon is 32 inches, and since it has 8 sides, then the length of one side of the figure is 32/8 or 4 inches.
"Regular" = all sides are the same length"Octagon" = it has 8 sidesEach side = 25 cmPerimeter = 8 x 25 cm = 200 cm
We searched as far below as possible and were unable to find the octagon.
The perimeter of a octagon is the sum of all its sides.
It is the sum of the lengths of the octagon's eight sides.
You say these things to yourself: -- "The perimeter is the distance all the way around the octagon." -- "The octagon has eight sides." -- "So, if it's a 'regular' octagon, then all the sides are the same length, and each side must be 1/8 of the perimeter." -- If it's not a 'regular' octagon, then it has some longer sides and some shorter ones, and the perimeter doesn't help me find the lengths of the sides.
The perimeter is 56.
Providing that it is a regular octagon with 8 equals sides then its perimeter is 8 time 8 = 64 cm
The perimeter of an octagon is the distance around its outside, so it is the sum of the lengths of each of its eight sides.
32cm.
It is the sum of its 8 sides
Perimeter = 8*15 = 120 cm
Perimeter = 8*7 = 56 cm
pentagon
8 (measure of each side) x 8 (total sides of an octagon) = 64cm
