Vedclass · Answer

(C) Step $1$: According to the rules of significant figures in addition,the final result should be reported to the same number of decimal places as the term with the fewest decimal places.Step $2$: Here,$L = 2.331 \ cm$ has $3$ decimal places and $B = 2.1 \ cm$ has $1$ decimal place.Step $3$: The sum is $L + B = 2.331 + 2.1 = 4.431 \ cm$.Step $4$: Since the term with the fewest decimal places $(B = 2.1 \ cm)$ has only $1$ decimal place,the result must be rounded to $1$ decimal place.Step $5$: Rounding $4.431 \ cm$ to $1$ decimal place gives $4.4 \ cm$.

If $L = 2.331 \ cm$ and $B = 2.1 \ cm$,then $L + B =$ (in $cm$)
