I am trying to remember how I would go about solving an equation like so.(adsbygoogle = window.adsbygoogle || []).push({});

What is the smallest perimiter of a rectangle with area of 64 cm^2.

I know I can use the graphing calculator.

So I know there are two sides, x and 64 / x.

If I try and graph x(64/x) I just get a straight line at 64. So how does one go about solving a question like this?

Thank you.
