Answer:
11.5 meters
Explanation:
Since we know the perimeter of a hexagon, and we know in a hexagon there are 6 equal sides, then we can find the length of each side.
P = 6*x, where P is the perimeter and 6 is the total amount of sides and x is the length of each side. Plug in 69 for P and solve your equation.
69 = 6x
Divide by 6 on both sides to isolate x
11.5 = x
