Step-by-step explanation:
 The area of a rectangle can be calculated with the formula:
 
 l: the length of the rectangle.
 w: the width of the rectangle.
 
 The area of the remaning wall after the mural has been painted, will be the difference of the area of the wall and the area of the mural.
 
 Knowing that the dimensions of the wall are  by
 by  , its area is:
, its area is:
 
 
 As they are planning that the dimensions of the mural be  by
 by  , its area is:
, its area is:
 
 
 Then the area of the remaining wall after the mural has been painted is:
 
 
        
             
        
        
        
(4(2)=8*8*8=512÷6=85.333333
(4-2)=2
8-2=6
8*2=16
8÷2=4
8+2=10
whichever operation it is
 
        
        
        
We are given the following equation:

Subtract both sides by 17

Take the positive/negative square root of both sides

This should be your answer. Let me know if you have any questions, thanks!
