Answer 1

Okay so all you have to do is add all of them together. Which I got 46. But then you need that question mark one. Use 17 cause that’s the length of the other side and subtract it by 5 because that’s how much less the other side is so 12. Add 12 to 46 and you get 58.

Answer 2

17-5=11
Then you add all the numbers up and you get 58
So the answer is 58 for the perimeter and 11 for the missing side
