Answer:
Each side of the model is 15 feet long.
The model is proportional to the original hexagon.
Explanation:
The scale factor is 6. Since scale factor = new length/original length,
new length = scale factor × original length = 6 × 2.5 feet = 15 feet.
Also, since the each side of the hexagon increases by a constant factor of 6, the model is proportional to the original hexagon.
