Answer:
P = 4×n or P = 4n
P is the total length of the square and n is the length of one side
Explanation:
Perimeter means the distance around the square. Since a square has four equal sides, you can figure out the total by multiplying one side by 4.
That could look like P = 4×n or P = 4n
4n means n+n+n+n. It's usually quicker to multiply then to add.
