Answer:
No.
Step-by-step explanation:
The two smallest sides must be greater than the biggest side when added up in order to form a complete triangle.
1+3 is 4, which is less than five, so the triangle wouldn't be connected.
Essentially, imagine a triangle where one line is too short to reach the other two, which is what was just explained--the smallest sides must add up to be greater than the biggest side in order to form a complete triangle.
Infinitely many solutions.
I drew up a (bad looking but still useful) grid and it proves the answer to be neither. even if the lines went continued in each direction it shouldn't be possible
N^2 because 2n is the same as n+n, but n^2 is the same as the product of n and n
