wouldn't it just be 2cm times 10 so the answer is20cm
A decagon has 10 equal sides, so if the perimeter is 120 cm each side must be 12 cm
170 cm
Regular = all sides equal so all sides of 25 cm. Decagon = 10 sides. So perimeter = 10*25cm = 250 cm.
To find the perimeter of a rectangle, you can use the formula: Perimeter = 2(length + width). For a rectangle that is 14 cm long and 4 cm wide, the perimeter would be: 2(14 cm + 4 cm) = 2(18 cm) = 36 cm. Therefore, the perimeter is 36 cm.
The answer is 12 cm.
If it's a regular decagon then its perimeter is 10*25 = 250 cm
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.
100 cm
11.4 cm
A decagon has 10 equal sides, so if the perimeter is 120 cm each side must be 12 cm
170 cm
Regular = all sides equal so all sides of 25 cm. Decagon = 10 sides. So perimeter = 10*25cm = 250 cm.
Perimeter = 2+2+2+1.5+2.5 = 10 cm
387.5 centimeters (10 sides each the same length)
To find the perimeter of a rectangle, you can use the formula: Perimeter = 2(length + width). For a rectangle that is 14 cm long and 4 cm wide, the perimeter would be: 2(14 cm + 4 cm) = 2(18 cm) = 36 cm. Therefore, the perimeter is 36 cm.
The perimeter of a 12 cm x 3 cm rectangle is 2*(12+3) cm = 2*15 cm = 30 cm.The perimeter of a 12 cm x 3 cm rectangle is 2*(12+3) cm = 2*15 cm = 30 cm.The perimeter of a 12 cm x 3 cm rectangle is 2*(12+3) cm = 2*15 cm = 30 cm.The perimeter of a 12 cm x 3 cm rectangle is 2*(12+3) cm = 2*15 cm = 30 cm.
