Final answer:
The total length of rope that Naomi has is the sum of the lengths of the three pieces. Adding 3 inches, 4 inches, and 5 inches gives a total of 12 inches.
Step-by-step explanation:
To find the total length of rope that Naomi has, we simply need to add the lengths of each piece together. The pieces of rope have lengths of 3 inches, 4 inches, and 5 inches respectively.
- Length of the first piece: 3 inches

Add the lengths: 3 inches + 4 inches + 5 inches = 12 inches.
Therefore, the total length of the rope is 12 inches.
