I think the answer would be D.
There is 30 students from each grade so we have 30/120 already then add 12 from 9th grade math and add 10 more from 10th grade math, then add 7 from 12th grade math.
30 + 12 + 10 + 7 = 59
59/120 students.
The perimeter is 44.5
The area is 72.25
For this case we have by definition, that if two lines are parallel then their slopes are equal.
We manipulate the equations algebraically to take them to the form y = mx + b.
Equation 1:

Thus, the slope of this line is 
Equation 2:

The slope of this line is -3.
As the slopes are not equal, then the lines are not parallel.
Answer:
False
