Perimeter = 2(l+b)
170 = 2(x+x+15)
170 = 2(2x+15)
170 = 4x+30
140 = 4x
x = 35 meters
Area = LxB => 35x(35+15)
Area = 35x(50)
Area = 1750 meters
Area of the largest plot = 1750/3
=> 583.'3' meters
$187.52 is 6.24% off of 200 and the amount saved is $12.48. If this is not what you meant let me know. The math is $200 × (1 - 6.24) = $187.52. Hope this helps!
Using the t-distribution, it is found that the test statistic for the hypotheses test is given by:

<h3>What are the hypotheses tested?</h3>
At the null hypotheses, it i tested if the mean difference remains the same, that is:

At the alternative hypotheses, it is tested if it has decreased, hence:
.
<h3>What is the test statistic?</h3>
The test statistic is given by:

The parameters are:
is the sample mean.
is the value tested at the null hypothesis.
- s is the standard deviation of the sample.
The parameters are given as follows:
.
Hence the test statistic is given by:

Your question is so blur i cant see
plzz send a nice pics
