The next step for Sage to express the value she multiplied in proper significant digits is to round up the area to the correct number of significant figures.
<h3>What is significant figures?</h3>
Significant figures are digits that is meaningful with respect to the precision of a measurement.
In other words a digit that is nonzero, followed by a nonzero digit, or (for trailing zeroes) justified by the precision of the derivation or measurement.
