The dimensions for this rectangle are b= 30 ft and h=20 ft.
<h3>Perimeter</h3>
The perimeter of a geometric figure is the sum of its sides.
The question gives:
- the geometric figure - rectangle
- the total perimeter - 120 ft
Therefore for the perimeter, you have
P= 
+ h+ h +h
P=2b+3h
2b+3h=120 (1)
From equation 1, you can write:
2b=120-3h
b=
b= 60 - 
(2)
The area for the rectangle is given by A= bh. Therefore, by replacing (2) in the formula for rectangle area, you have:
The maximum area will be calculated from the derivation of the previous equation of area.
The maximum area can be found when the first derivative is equal to zero. Thus,
60-3h=0
-3h=-60 *(-1)
3h=60
h=20
Now, you know the height and from equation 2 (b= 60 - ) you can find the base.
b= 60 -
b=60 - 3*10
b=60-30
b=30

Step-by-step explanation:
Given that we want to estimate average income in a population.
The standard deviation of income in the population is $1,000
We want confidence interval around our estimate to be +/- $40
i.e Margin of error = 40
We know that margin of error = Std error * Z critical for 95%
i.e. 
Std error = 
Together we get

The consumption of electricity in May based on the model will be 1225kw.
<h3>How to calculate the consumption?</h3>
The model that's given to calculate the consumption is:
C = 1200 + 5t
May = 5th month
The consumption in May will be:
C = 1200 + 5t
C = 1200 + 5(5)
C = 1200 + 25
C = 1225Kw
In conclusion, the consumption of electricity in May based on the model will be 1225kw.

Well, I would just reverse it. It seems you just have to reverse the whole problem.
