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.
The answer is 12 cm.
Consider a square with sides of length x cm whose area is x2 cm and perimeter is 4x cm. Next consider a rectangle with sides of 2x cm and x/2 cm. It area is 2x*x/2 = x2, the same as for the square. But its perimeter is 2*(2x+x/2) = 5x > perimeter of the square. Perimeter of 3x * x/3 = 62/3x cm. Perimeter of 100x * x/100 = 200.02x cm Perimeter of 1000000x * x/1000000 = 2000000.000002x cm. As you can see, it is possible to increase the perimeter without limit.
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)
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.
