Answer:
   4√41 ≈ 25.61 feet
Step-by-step explanation:
The shortest route is the one that crosses the longest edge between room surfaces. In this case, that is the 16-foot edge between the floor and wall opposite the amplifier, or the 16-foot edge between the ceiling and the wall adjacent to the amplifier.
The length of the required wire is ...
   √((8+12)² +16²) = √656 = 4√41 ≈ 25.61 . . . feet
 
        
             
        
        
        
The area of a triangle is 1/2 bh
so to find the area of the larger triangle do the following calculation:
1/2 time 12 time 7. that will give you 42 ft squared.  that is the larger triangle. 
the next way to find the area i will show you is:
pretend that the the triangle is inside of a rectangle. now you have 4 triangles. you know that the base of the rectangle is 15 ft anf the height is 7. now take the smaller triangle and it has its rectangle base 3 and height 7. multiply to get 21 feet squared. divide by 2 since there are 2 triangles in the small rectangle. 10.5 feet squared
        
             
        
        
        
If we want to compute  , we have to substitute every occurrence of
, we have to substitute every occurrence of  with
 with  in the definition of the function:
 in the definition of the function:

Similarly, computing  means to substitute the input with 2:
 means to substitute the input with 2:

So, we have

And finally
