The mistake is made on line 3, after calculating 35/7, he should have started with the multiplication 6(2)
The length and breadth(width) of the pool are
Let
From the question, we can build the following relationships
subtracting to eliminate 
(we do not even need it!)
we can also build another relationship from the question. Since the area of the strip equals the area of the pool:
We have two unknowns, 
and 
. Eliminate
If we solve the quadratic equation for , we get
and
The length and breadth(width) of the pool are
