Question
Transcribed Image Text:A triangle has sides of 3.5 inches, 6 inches, and 5.5 inches. What is its perimeter?
- ○ 18 inches²
- ○ 15 inches
- ○ 12 inches
- ○ 15 inches²
**Explanation:**
The perimeter of a triangle is the sum of the lengths of its sides. For this triangle, add all side lengths together:
3.5 inches + 6 inches + 5.5 inches = 15 inches
Therefore, the correct answer is 15 inches. Note that answers given in square inches (inches²) indicate area, not perimeter, and are irrelevant in this context.
