What is the perimeter of a square with an area of 324 cm2?

To find the perimeter we must first find the length of the sides. How to do this is shown below:

The formula for the area of a square is:

A = s²

Area = side²

We know that area (A) is 324

324 = s²

Now we must find the length of the side (s). To do this we must get rid of the square. To remove the square from s take the square root of both sides:

√324 = √s²

18 = s

Each side of the square is 18 cm

Now we can find the perimeter of the square using the formula:

P = 4s

P = 4(18)

P = 72

The perimeter of a square with an area of 324 cm² is C. 72 cm

Hope this helped!
