Final answer:
Turner should use a measuring tool like a tape measure to measure the length of the ribbon, and then cut the other pieces to the same length.
Step-by-step explanation:
To measure the length of the ribbon, Turner should use a measuring tool like a tape measure that can measure in feet. Since he needs 9 pieces of ribbon with the same length, he should measure one piece and then cut the other 8 pieces to the same length as the initial measurement.
