Answer:

[tex]l= \frac{A}{2h} -w[/tex]

Step-by-step explanation:

The question is not correct (particularly the expression for the area)

 A=2lh+2wh

Now we are expected to solve for l, that is we are going to make l subject of the formula, we have

let us take the second term on the RHS to the LHS

[tex]A-2wh= 2lh[/tex]

we can now divide both sides by 2h we have

[tex]\frac{A-2wh}{2h} = l\\\\l=\frac{A}{2h} -\frac{2wh}{2h} \\\\l= \frac{A}{2h} -w[/tex]

hence the expression for the length is  [tex]l= \frac{A}{2h} -w[/tex]
