Answer:
   75 in^2
Step-by-step explanation:
The central vertical rectangle (including "ears") has dimensions 
   3 in wide by (9+2+2) = 13 in tall
Its area is 
   A = LW = (3 in)(13 in) = 39 in^2
__
The two rectangles either side of that have dimensions 2 in by 9 in. The area of each of them is 
   A = LW = (2 in)(9 in) = 18 in^2
__
The total net area is the sum of the areas of the parts:
   left rectangle + central rectangle + right rectangle
   = 18 in^2 + 39 in^2 + 18 in^2 = 75 in^2 . . . . surface area of the net
