Answer:
If width = 60 m, length = 195 m.
If width = 150 m, length = 465 m.
Step-by-step explanation:
The area of a rectangle is l * w or length times width.
So we can set an equation (letting w = width and x = length)
w = 
Part 1: width = 60m:
60 = 
65 = 
x = 195 m
Part 2: width = 150 m:
150 = 
155 = 
x = 465 m

And the margin of error with this one:


Step-by-step explanation:
Assuming that the parameter of interest is the sample mean
. And we can estimate this parameter with a confidence interval given by this formula:
(1)
For this case the confidence interval is given by (1.9, 3.3)
Since the confidence interval is symmetrical we can estimate the sample mean with this formula:


And the margin of error with this one:
