Total students = 28
Students with brown eyes = 19
students wear glasses = 13
Not brown eyes or no glasses = 7
Not brown eyes = 28 - 19 = 9
Not wearing glasses = 28 - 13 = 15
Not brown eyes and wearing glasses = 15 - 9 = 6
Brown eyes and wearing glasses = 13 - 6 = 7 <==== answer
Answer:
-45
Step-by-step explanation:

3(2(-6)-3) = 3(-12 -3)= 3(-15) = -45
It would be 75 units in length and 18 units in width.
