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!

Answer:
children = 67
Step-by-step explanation:
two equations can be derived from this question
x + y = 85 equation 1
3x + y = 121 equation 2
where x = number of adults
y = number of children
subtract equation 1 from 2
2x = 36
x = 18
substitute for x in equation 1
y = 85 - 18 = 67
In finding the minimum amount of time that Brandon can swim is to add the quotient of the distance to swim and its velocity and the quotient of the difference of 250 and the distance cover in running and its velocity. The minimum time is 43.33 seconds
