100 cm
If it's a regular decagon then its perimeter is 10*25 = 250 cm
A decagon has 10 sides. If it is a regular decagon, all of the sides are the same length. Each side would be 0.8 yards or 2.4 feet in length.
3.2 X 10 = 32cm
it willl be 11.4 because you are supposed to divide 114 with 10 wich equals 11.4.
decagon
10*length of a side.
A decagon has 10 sides, therefore, with side length 13.5 centimetres, the perimeter would be 13.5 x 10 = 135 centimetres.
It is: 58/10 = 5.8 units of length
If it's a regular decagon then its perimeter is 10*25 = 250 cm
8 yds * * * * * That is simply nonsense. In a regular decagon, each of the 10 sides is of the same length. So the length of each side is 22/10 = 2.2 feet.
A decagon has 10 sides. If it is a regular decagon, all of the sides are the same length. Each side would be 0.8 yards or 2.4 feet in length.
A decagon has 10 sides. If each side is 17.2 cm, then the perimeter will be 10 x 17.2 cm Which is 172 cm.
3.2 X 10 = 32cm
A decagon has 10 equal sides, so if the perimeter is 120 cm each side must be 12 cm
12cm a decagon is 10 sides 120/10=12
Regular = all sides equal so all sides of 25 cm. Decagon = 10 sides. So perimeter = 10*25cm = 250 cm.
A decagon is a 10-sided figure. If each side is 9.9 feet long, the perimeter of the decagon, which is the sum of all sides, is 10 x 9.9 feet or 99 feet.
