The maximum error in the calculated area of the rectangle is
Step-by-step explanation:
The area of a rectangle with length and width
is
so the differential of <em>A</em> is
so
We know that each error is at most 0.1 cm, we have ,
. To find the maximum error in the calculated area of the rectangle we take
,
and
,
. This gives
Thus the maximum error in the calculated area of the rectangle is
