By definition, the perimeter of a square is given by:
Where,
L: length of the sides of the square.
When the sides of the square are tripled, the equation changes as follows:
Then, rewriting the equation we have:
Where,
P: perimeter of the original square.
Therefore, we can conclude that the perimeter is tripled.
Answer:
The perimeter of the square is tripled.
Since we are not given any information about the proportion, we will assume the sample proportion to be 0.50
so,
p = 0.50
The Error is 10% percentage point. This means that on either side of the population proportion the error is 5% so E = 0.05
z = 1.645 (Z value for 90% confidence interval)
The margin of error for population proportion is calculated as:
This means 271 students should be included in the sample
