The smallest possible whole number length for the third side is 7
Data obtained from the question
- 1st length = 5
- 2nd length = 11
- 3rd length =?
How to determine the smallest possible length of the 3rd side
Case 1
1st + 2nd > 3rd
5 + 11 > 3rd
16 > 3rd
3rd length < 16
Case 2
1st + 3rd > 2nd
5 + 3rd > 11
3rd > 11 - 5
3rd > 6
Thus, we have
6 < 3rd length < 16
Since the 3rd length is greater than 6, then the smallest possible length for the 3rd side is 7
