Area of a rectangle is just length x height.
It probably looks confusing because of the numbers. So just change them into only inches; 12 inches in a foot.
So the rectangle is 10ft, 10inches tall...or 10*12+10=130inches
The rectangle is 2ft 11inches wide...or 2*12+11=35 inches
So now just multiple 130*35=4550 inches^2

Answer:

Option B) 9.1      

Step-by-step explanation:

We are given the following in the question:

Average score = 490.4

Standard deviation = 63.7

Sample size, n = 49

Formula:

=\dfrac{\sigma}{\sqrt{n}}

Putting values, we get,

Standard error =

I'm confused, can someone help?

To solve for S, you would want to get rid of the denominator so multiply 360 onto both sides. then the equation is 360A=pi times r squared times S. Divide both sides by pi and r squared and you get S=360A/pi times r squared
