Find the perimeter of the octagon if each side is 3.85 cm long.

If a figure has eight corners, then this means that it also has eight sides.

Therefore, to find the perimeter of such a figure, it is necessary to multiply the number of sides of the octagon by the length of one of its sides.

We have that one side of the figure is 3.85 cm, and the total of the sides is 8.

Multiply 8 by 3.85 cm.

8 * 3.85 cm = 30.8 cm – the perimeter of this rectangle is equal.

Answer: the perimeter of the specified figure with the length of one side is 3.85 cm, and the number of sides is 8, is equal to 30.8 centimeters.
