Final answer:
Each piece of streamer is approximately 3.11 feet long.
Step-by-step explanation:
To find the length of each piece of streamer, we need to divide the total length of the streamer (28 feet) by the number of equal sections (9). This will give us the length of each section.
28 feet ÷ 9 sections = 3.11 feet per section.
Therefore, each piece of streamer is approximately 3.11 feet long.
