## Homework Statement

I've been given a list of lengths of the side of a small metal sheet in the shape of a square. The length of the side of this square sheet varies with temperature. I have to calculate areas for each length and then calculate the average area. What should be the uncertainity and number of significant figures in the average area if the length with least sig figs has 8 significant figures. Is the uncertainity in average area related to the standard deviation in any way.

## Homework Equations

Area of a square = length^2

## The Attempt at a Solution

Calculated the average area using the calculator but it gives over 14 sig figs whereas the least sig figs in a length entry are just 8.
