Step-by-step explanation:
To find the sum of the given lengths, we simply need to add all of them together.
Here's how it's done step by step:
- First, list down all the lengths: 9.5 ft, 3.8 ft, 10.7 ft, 4.7 ft, 4.7 ft, 9.5 ft, 4.7 ft, 4.7 ft, 10.7 ft, and 3.8 ft.
- Next, you add them together: 9.5 + 3.8 + 10.7 + 4.7 + 4.7 + 9.5 + 4.7 + 4.7 + 10.7 + 3.8.
- After performing the addition, the sum is 67.1 ft.
Therefore, the total length when you add up all the lengths mentioned is 67.1 feet.
