Answer: 42
Step-by-step explanation: you would do 63 divided by 3 then you would get 21 and do 21×2 and get 42
This is a square, and so all the sides will be the same measurements. Note that you are given an area, so you'll have to root the total area to get a side.

Answer:
95%
Step-by-step explanation:
The empirical rule states that if data follows normal distribution then the percentage of observations falls within one, two and three standard deviation around the mean are
i) 68% falls within one standard deviation
ii) 95% falls within two standard deviation
iii) 99.7% falls within three standard deviation.
Hence 95% of the observations will fall within two standard deviations around the mean if the data follows normal distribution.
