You have 4 walls, 2 with length 12 feet, 2 with length 15 feet and each of them has a height of 12 feet
so you sum all the lengths and then multiply it by the height to get the total area
total length=2*(12+15)
=2*(27)
=54
total area=total length*ceiling height
=54*12
=648 feet^2 to cover all walls with wallpaper
        
             
        
        
        
Answer: 10(2)=20 and 4(3)=12 
Step-by-step explanation:
1) Divide 20 by 2 which would be 10 that gives you the sum of F
2) Divide 12 by 3 which is equals 4 so thats the sum of F for f(3)=12
 
        
             
        
        
        
51*32/102=32/2=16.
