Because we're treating the swimming pool as a standard rectangle, rather than a three dimensional shape, we can use the formula L * W = A to calculate the length of the pool.
Length * Width = Area
We've established two key bits of information, and with them we can solve for the final piece.
Length * 4 = 16
4l = 16
Divide both sides by 4.
l = 4
<h3>The length of the pool is 4 meters.</h3>
 
        
                    
             
        
        
        
Yes it is a function Bc the x values don’t repeat

Her statement is possible, the first rectangle could be equal to the second  because x is unknown so if x was 5in in the first rectangle and - 1 in the second rectangle both problems would look like this 2 in & 5 in and the second one 5in & (2 in =  (-1 +3)).
        
             
        
        
        
Step-by-step explanation:
△BAC ≅ △EDF (given)
Therefore,
BC=EF
x-4=19
x=23
