Answer:
Divide the perimiter by 4.
Step-by-step explanation:
Because the sides of a square are all equal, and there are 4 of them, you would take the perimeter, which is the total measure of all of the sides, and divide that number by 4, the amount of sides on a square.
[tex]\large\boxed{a=\dfrac{P}{4}}[/tex]
Divide the perimeter by 4.
The formula of a perimeter of a square:
P = 4a
a - length of a side
Solve for a:
[tex]4a=P[/tex] divide both sides by 4
[tex]a=\dfrac{P}{4}[/tex]
