<span>B would be the most appropriate response for this. We don't need to worry about Ashley being in the 85th percentile, that is just extra information they have provided us. What we need to look at is her mean test score is 180, so that is the average score she normally gets on her tests, but then they say she has a standard deviation of 15 which means her scores are normally no lower than 165 and no higher than 195 because she normally doesn't deviate or change her score more than 15 points for her normal 180. So if you take 180 minus 15 you get 165 and if you take 180 plus 15 you get 195, therefore we can determine that the most appropriate answer would be between 165 and 195. The only option that fits in this category is B 185</span>

We will represent the length of the rectangle as 
and the width as 
.
From this problem, we can say 
. We can also deduct an equation from the second sentence:
(from substitution)
Using this value for , we can find :
The length of the rectangle is 23 cm and the width of the rectangle is 18 cm.
