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
Perimeter of the square: 17+17+17+17 = 68 cm
The perimeter of a triangle is the sum of its 3 sides.
wouldn't it just be 2cm times 10 so the answer is20cm
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.
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
Perimeter of the square: 17+17+17+17 = 68 cm
If each side of the square is 17 cm then its perimeter is 4*17 = 68 cm
387.5 centimeters (10 sides each the same length)
A pentagon has 5 sides A regular pentagon has all sides equal → perimeter of regular pentagon with side 17 cm = 5 × 17 cm = 85 cm
