The first thing we must do is find the percentage that has traveled outside of the United States.
For this, we make the following rule of three:
30 ---------> 100%
9 -----------> x
We clear the value of x:
x = (9/30) * (100)
x = 30%
Then, for 120 sixth graders in the school we have:
(0.30) * (120) = 36
Answer:
36 students have traveled outside of the united states

Step-by-step explanation:
Shape C is A trapezoid
Area of trapezoid = 
where a and b = base lengths and h = height
The trapezoid has the following dimensions
base 1 = 3 units
base 2 = 5 units
height = 4 units
Using these dimensions we plug in the values into the formula stated above.

Hence the area of shape C = 16 square units
