Answer:
G. 7600 
Step-by-step explanation:
Step 1: Deconstruct the shape
2 rectangles with dimension of 50 cm x 20 cm
2 rectangles with dimension of 40 cm x 20 cm
2 rectangles with dimension of 40 cm x 50 cm
Step 2: Find surface area of the shapes
2(50 x 20) = 2000 
2(40 x 20) = 1600 
2(40 x 50) = 4000 
Step 3: Add the surface areas together
2000 + 1600 + 4000 = 7600 
Therefore the surface area is 7600
and the answer is G.
Well what I would do first is divide the 900 student by the 445 teacher to get 20 students per teacher. Now I would take that 20 and multiply it by 110 teacher to get 2200 Students.
Answer= C) 2200 Students
These are the same line when you graph. So there are infinite solutions to this system.
