Answer:
To calculate the standard deviation of those numbers:
Work out the Mean (the simple average of the numbers)
Then for each number: subtract the Mean and square the result.
Then work out the mean of those squared differences.
Take the square root of that and we are done!
Let length be (l) and width be (w).
According to the question, l=3w+3......equation1
And perimeter that is 2(l+w) =94........equation2
Solve these two equations, you get your answer.
l=36
w=11
