Answer:

Step-by-step explanation:

If the perimeter of a regular octagon is 72 meters, then we can find the measure of one side by dividing the perimeter by the number of sides.

Since an octagon has 8 sides, the measure of each side is:

72 meters ÷ 8 sides = 9 meters

Therefore, each side of the regular octagon is 9 meters long.
