The brown shelf is 11 feet long.
Solución
To determine the length of the brown shelf, follow these steps:
1. **Convert the Orange Shelf Length to Inches:**
- **Feet to Inches:**
1 foot = 12 inches
5 feet = 5 × 12 = **60 inches**
- **Add the Remaining Inches:**
60 inches (from feet) + 6 inches = **66 inches**
2. **Calculate Twice the Length for the Brown Shelf:**
- **Double the Total Inches:**
66 inches × 2 = **132 inches**
3. **Convert Inches Back to Feet and Inches:**
- **Feet from Inches:**
132 inches ÷ 12 inches/foot = **11 feet**
- **Remaining Inches:**
132 inches - (11 feet × 12 inches) = 0 inches
4. **Final Answer:**
The brown shelf is **11 feet** long.

Bonus Knowledge
To find the length of the brown shelf, we first need to convert the length of the orange shelf into inches. There are 12 inches in a foot, so 5 feet 6 inches is calculated as (5 x 12) + 6 = 60 + 6 = 66 inches. Since the brown shelf is twice as long as the orange shelf, we multiply 66 inches by 2, giving us 132 inches. Now, converting 132 inches back into feet, we find that it is 11 feet long (as 132 divided by 12 equals 11). So, the length of the brown shelf is 11 feet!
