Hello, DarkestEvil!

A page contains 32 inē of print.

The margins at the top and the bottom of the page are 2 inches.

The margins on each side are only 1 inch.

Find the dimensions of the page so that the least paper is used.

I was taught to write two equations, one for perimeter and one for area.

No, that is for a specific (and different) problem. Code:

: 1 : - x - : 1 : -
_ *---------------* -
: | | :
2 | | :
: | | :
- | *-------* | :
: | |///////| | :
: | |///////| | :
y | |///////|y | y+4
: | |///////| | :
: | |///////| | :
- | *-------* | :
: | x | :
2 | | :
: | | :
- *---------------* -
: - - x+2 - - :

Let: = width of printed area.

Let: = height of printed area.

We are told that: .

The width of the page is: .

The height of the page is: .

The area of the page is: .

Substitute [1]: .

And we have: .

And *that* is the function we must minimize.
