Answer:

Step-by-step explanation:
Ok so we have 2 (congruent) triangles and 3 rectangles. 
Your main approach to this problem should be to find the area of each of the faces and adding them up to get to your final answer. Your question makes a point of including the correct unit in your answer. Since this is surface area, the unit would be 
Now let's start: 
First, I am going to start with finding the area of the rectangles. 

Alright, next lets move on to the triangles. 
They are both the same, if you notice. So find one and double it. 

now lets add em all 
330+60
= 390 and thats your final answer, dont forget to include the unit, ft^2
 
        
             
        
        
        
Answer:
x=0.5
Step-by-step explanation:
32x+16=32
        -16    -16
32x=16
÷32 ÷32
x=0.5   or    x=1/2
