Answer:
y=(-2/5)x
Step-by-step explanation:
Assuming that the goal is to find the linear equation in slope-intercept form, this problem is pretty simple.
Slope intercept form is y=mx+b, where m is the slope and b is the y-intercept. We just have to plug in the information
y=(-2/5)x+0
Simplifies to:
y=(-2/5)x

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
