The perimeter of the octagon is 24 cm. Make an equation and solve it.

First of all, let us recall that for each polygon, the statement is true that the number of its corners is equal to the number of its sides.

In this case, if we are talking about a regular octagon (i.e., in which all sides and interior angles are equal), it is possible to find the length of its side using the equation.

Let the side length of the octagon be x cm.Then the perimeter of this figure can be written as follows:

8 * x = 24;
x = 24: 8 = 3 (cm).

Answer: The length of the side of the octagon is 3 cm.
