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)
Perimeter = 5*5 = 25 cm
Perimeter = 3*25 = 75 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
Since it is a square, all four sides are the same. The side is sqrt(25 cm2) = 5 cm. The perimeter is 4 x 5 cm = 20 cm.
