Area of the rectangle is equal to length times width
In function notation, the Area of the rectangle function is a function in variables l (length) and w(width) as follows:
A(l, w)= l*w
for A=475 we have,
l*w=475
or 
, each are equivalent, and each represent the inverse variation.

Answer:
The general form of a solution of the differential equation is already provided for us:
where . We now want to find a solution
such that
and
. Therefore, all we need to do is find the constants
and
that satisfy the initial conditions. For the first condition, we have:
For the second condition, we need to find the derivative first. In this case, we have:
Therefore:
This means that we must solve the following system of equations:
If we add the equations above, we get:
If we now substitute into either of the equations in the system, we get:
This means that the solution obeying the initial conditions is:
Indeed, we can see that:
which do correspond to the desired initial conditions.
