## Homework Statement

What is the smallest perimeter for a rectangle with an area of 16, and what are its dimensions?

## Homework Equations

A=L*W

P=2W+2L

## The Attempt at a Solution

I managed to get the perimeter equation down to one variable like so:

Area is 16.

A=LW

16=LW

16/L=W

P=2L+2(16/L)

P=(2L

^{2}+32)/L

and this is where I stop. I just don't see how this can be applied to the situation stated.
