Since the ratio of students with green eyes to students with blue eyes in the graph is 20/10, we can see that there is 1 blue eyed student for every green eyed student. Meaning that there will be half as many blue eyed students as green eyed students. So if there are 300 students we know that there will be 150 blue eyed students.

Area of square is
9 x 9 = 81
Area of first triangle is
12x9/2= 54
Area of Second triangle is
12x9/2= 54
81+ 54+54= 189
The answer is 188
<u><em>Answer:</em></u>
108 square units
<h3><u><em>
Step-by-step explanation:</em></u></h3>
3 x 4 = 12
3 x 4 = 12
6 x 3 = 18
6 x 3 = 18
6 x 4 = 24
6 x 4 = 24
24(2) + 18(2) + 12(2) = 108 square units
Therefore, the surface area of the rectangular solid below using its net is <u>108 square units</u>
