If it's a regular decagon then its perimeter is 10*25 = 250 cm
Perimeter = 5*5 = 25 cm
100 cm
Then the square will have 4 equal sides of 5cm with a perimeter of 20cm and an area of 25 square cm
The perimeter is 7 cm
The perimeter of a rhombus is the sum of its 4 sides
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.
Regular = all sides equal so all sides of 25 cm. Decagon = 10 sides. So perimeter = 10*25cm = 250 cm.
170 cm
A decagon has 10 equal sides, so if the perimeter is 120 cm each side must be 12 cm
387.5 centimeters (10 sides each the same length)
To find the perimeter of a pentagon, you simply multiply the length of one side by the number of sides. Since each side of the pentagon is 25 cm and there are 5 sides, the perimeter is calculated as follows: 25 cm × 5 = 125 cm. Therefore, the perimeter of the pentagon is 125 cm.
Perimeter = 3*25 = 75 cm
Perimeter = 5*5 = 25 cm
100 cm
The perimeter of anything is the distance around it SO ... since a pentagon has 5 sides, the perimeter would be ... 5 (sides) X 5 (cm per side) = 25 cm.
11.4 cm
31 cm 31+34+25 = 90
