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

Answers:
Expression for the total number of quarters is 40*1.20
Amount of money you have left is 6 dollars
===================================================
Explanation:
You start with 40 quarters. 20% of this is 0.20*40 = 8 which means you found 8 more quarters. The total goes from 40 to 40+8 = 48.
A slight shortcut is to write 40*1.20 = 48
--------------
48 quarters = 48*0.25 = 12 dollars
Or you can divide by 4 to determine the total value of the quarters in dollars.
If you spent half (50%) of that money, then you'll be left with 6 dollars.
