The Length of the rectangle is 18 unit.
<h3>
What is the Perimeter of a Rectangle?</h3>
Perimeter of rectangle = 2(length + width)
Given the following:
Let x represent the width of the rectangle
Width of the rectangle = x
Length of the rectangle = 4x + 6
Perimeter of rectangle = 42 units
Therefore, we would write the following equation to find x based on the formula for finding the perimeter of a rectangle:
2(4x + 6 + x) = 42
2(5x + 6) = 42
10x + 12 = 42
10x = 42 - 12
10x = 30
10x/10 = 30/10
x = 3
The width (x) = 3.
Length of the rectangle = 4(3) + 6
Length of the rectangle = 18 unit.

Answer:
Decrease the sample size.
Step-by-step explanation:
Margin of error is:
ME = CV × √(σ / n)
where σ is the population standard deviation, or:
ME = CV × √(p (1 − p) / n)
where p is the proportion.
In each case, the margin of error is directly proportional to the critical value, and inversely proportional to √n.
Lowering the confidence level will lower the critical value, which will decrease the margin of error. Decreasing the sample size will increase the margin of error.
