Answer:
[tex]\sqrt{40}[/tex]=s
Step-by-step explanation:
The area of a square can be found by multiplying two of the sides of the square. So P=s*s, of "Perimeter equals side length time side length". We also know that all the sides of a square are the same side, so the perimeter of the sqaure can be found using the square by doing p=[tex]s^{2}[/tex].
