I can't see a square or a D given with your question.
But to find the perimeter you just have to add the surface of every side of the square.
To covert degrees Fahrenheit (F) to degrees Celsius (C) we use the equation C<span> = (</span>F<span> - 32) × 5/9</span> . To convert degrees Celsius (C) to degrees <span>Fahrenheit (F) we have to rewrite the equation.
First step: Divide both sides by 5/9. The equation would look like this:
</span>C(9/5) = (F - 32)
Second step: Add 32 on both sides.
32 + (9/5)C = F or F = <span>32 + (9/5)C</span>

Multiply the rows by the spaces in each row. 20 x 15 = 300
Let 
be the number of students who eat cauliflower.
Therefore, 
.
Let 
be the total number of students surveyed.
Therefore, 
Thus, 
Now, for 90% confidence level, from the table we know that 
.
The formula for the interval range of proportion of students is :
Plugging in the values we get:
Thus, Jane is 90% confident that the population proportion p, for students who eat cauliflower in her campus is between 5.398% and 15.114% (after converting the answer we got to percentage).
18. Make the values have the same denominators.
4 2/3(8/8)= 112/24
5 3/8 (3/3)= 129/24
Add the values
112/24+129/24= 241/24
Simplify the answer
241/24= 10 1/24
The answer for question 10 1/24 ounces.
20. Multiply 1 1/4 by 5. (There are 5 days from Monday through Friday)
1.25(5)= 6 1/4
The answer to question 20 is 6 1/4.
Hope this helps!
