A square has an area of 40 units^2. Write an expression for the perimeter of the square.

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=.
