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!

The formula for the surface area of a cube is 6a^2, where a = the length of one edge. To get the cube's edge length, use the vertex coords given to you [(4, 8) and (12,16)]. From 4 to 12 is 8 points, so each edge of the cube is 8 points long. 6(8)^2 = 384, so your answer is C.
Answer:
q<392
Step-by-step explanation:
First, we turn words into an inequality. Then, we solve for q.
It is also a good idea to check our answer, to make sure it is reasonable and we did not make a careless mistake.
The value satisfies the equation, so this should be correct.
