1. A Triangle has a perimeter 13. The two shorter sides have integer lengths equal to x and x + 1. Which of the following could be length of the other side?
- A. 3
- B. 3
- C. 3
- D. 3
Answer: Option D
Explanation:
We know that the sum of the lengths of the shorter sides has to be more than the length of the longer one.
Looking at the options, we can't have 8 as the value for the longest side because then this side would be greater than the sum of the other two sides.
Similarly, we can't have 2 or 4 as values for the longest side as it wouldn't be the longest side then.
The correct answer is 6 here, where the other sides are 3 & 4.
