If a square has a side of 12xy+1, it’s perimeter is:

48xy+4

Step-by-step explanation:

Because we know that a square has 4 sides, we can multiply this expression by 4, thus ending in 48xy+4. Hope this helps :)

For this case we have by definition, that the perimeter of a square is given by the sum of its sides. As the sides measure the same, then the perimeter is:

Where "l" represents the side of the square:

Then, they tell us that:

So:

-22

times both sides by 2, times () by 8, add alile terms, move terms, add alike and caculate divide both sides by 3

126 maybe. sorry
