The perimeter of square tile is represented by [tex]p(x)=4x\\\\[/tex] and value of p(4) is 16 unit.
Since, Perimeter is the distance around the outside of a shape.
We know that all four sides of square are equal.
So that, perimeter of square tile is four times of side of square.
Therefore, [tex]p(x)=4x[/tex]
And [tex]p(4)=4*4=16 unit[/tex]
