Question

Anyone Willing to solve 33

Answer 1

The answer is P/2 - l = w

Answer 2

Start with

`P = 2(l+w)`

Expand the right hand side:

`P = 2l+2w`

Subtract 2l from both sides:

`P-2l = 2w`

Divide both sides by 2:

`(P-2l)/(2)=w`

And so we solved the equation for the width:

`w = (P-2l)/(2)`
