To find the standard deviation of the following data set
we use the following formula
Step 1: Find the mean .
The mean of a data set is the sum of the terms divided by the total number of terms. Using math notation we have:
Step 2: Create the below table.
Step 3: Find the sum of numbers in the last column to get.
Step 4: Calculate σ using the above formula.

I have attached a written explanation to help :).
Let's say each side of the square =
If we put 7 squares in a row to make the rectangle,
length of the rectangle =
Area of a rectangle = length multiplied by width
Area of rectangle = multiplied by
=
We are also told that the total area = 567
So
Now solve for .
Divide both sides by 7.
Then square root both sides to find
= 9
