The total change over the period will be 16 degrees F.
Answer:

Step-by-step explanation:
Let consider the following algebraical substitution:


The integral is re-arranged to this form:

After doing some algebraical manipulation, the rational form of this integral is:

The solution of this integral is:

Area of rectangle = length x width
Perimeter of rectangle = 2 x (length + width)
Now we know that perimeter of rectangle = 16
2(length + width) = 16
Length + width = 16/2
Length + width = 8
Now the value of length and width is that if we add both
values we have the answer 8.
So, here are some possible values of length and width and
also that length and width are odd numbers;
Odd numbers are = 1,3,5,7,….
7 + 1 = 8
5 + 3 = 8
So, either length is 7 and with is 1 or length is 5 and
width is 3
So area of rectangle = 7 x 1 = 7 or 5 x 3 = 15
Thus, the possible values of area of rectangle are 7 ft² and 15 ft².
