The perimeter of a square can be found using P=n+n+n+n, where n is the length of one side of the square. Which equation could also be used to find the perimeter of a square

P = 4×n   or  P = 4n

P is the total length of the square and n is the length of one side

Step-by-step 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.

total of apples - take away four

6-4 = 2

answer is 2 apples
