Here, you would complete it with the Pythagorean Theorem. 
So, A^2 + B^2 = C^2 
So 14^2 + B^2 = 14^2
This equals = B = 11.49
        
                    
             
        
        
        
Answer:

Step-by-step explanation:
We have been given that the rectangle has an area of  square meters and a length of
 square meters and a length of  . We are asked to find the width of rectangle.
. We are asked to find the width of rectangle.
Since we know that area of a rectangle is width times length of the rectangle, so we can find width of our given rectangle by dividing given area by length of rectangle.



Upon substituting our given values in above formula we will get,


Using exponent rule for quotient  we will get,
 we will get,


Therefore, width of our given rectangle will be 9x meters.
