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

A) 18 cm
B) 36 cm
C) 72 cm
D) 144 cm

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!
