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.
A regular decagon has 10 sides. See link.
''Decagon'' is any polygon with ten sides and ten angles ''Regular decagon'' is a polygon with ten sides of equal length and all angles equal to 144°
Exterior Angle for a decagon is 36 Degrees.
387.5 centimeters (10 sides each the same length)
If it's a regular decagon then its perimeter is 10*25 = 250 cm
Regular = all sides equal so all sides of 25 cm. Decagon = 10 sides. So perimeter = 10*25cm = 250 cm.
A decagon has 10 equal sides, so if the perimeter is 120 cm each side must be 12 cm
A decagon has 10 sides, therefore, with side length 13.5 centimetres, the perimeter would be 13.5 x 10 = 135 centimetres.
Five times the length of one of the sides.
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 regular decagon has 10 equal sides.
80 mm, 8·10=80. shift+option+9=·
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.
find the perimeter of a decagon if all off the sides equal 4mi.
A regular pentagon has five sides of the same length. Therefore, the perimeter of the shape will be 8 x 5 = 40 centimetres.
