The perimeter of a shape is the sum of all it sides.
The perimeter of the square is [tex]16x - 4[/tex]
Given that:
[tex]Length = 4x - 1[/tex]
The perimeter (P) of the square is:
[tex]P = 4 \times Length[/tex]
So, we have:
[tex]P = 4 \times (4x -1)[/tex]
Open brackets
[tex]P = 16x - 4[/tex]
Hence, the perimeter of the square is 16x - 4
