The smallest prime numbers are 1, 3 and 7. However they would not work to become a triangle, because the sum of the two shortest sides should be larger than the length of the longest side.

<span> 1+3 is less than 7 so it wouldn't work. </span>

The next set of prime numbers is 5,7,11 which I think is the answer since 5+7 is more than 11 and 5+7+11 is 23 which is prime.

 

Answers:

<span>23 is the smallest possible prime perimeter</span>
