If $L = 2.331\,cm,\;B = 2.1\,cm$, then $L + B = $
If $L = 2.331\,cm,\;B = 2.1\,cm$, then $L + B = $
$4.431 \,cm$
$4.43 \,cm$
$4.4 \,cm$
$4 \,cm$
If $L = 2.331\,cm,\;B = 2.1\,cm$, then $L + B = $
Given, $L = 2.331\;cm$
$ = 2.33$ (correct upto two decimal places)
and $B = 2.1\;cm$$ = 2.10\;cm$
$\therefore \;L + B = 2.33 + 2.10 = 4.43\;cm$.$ = 4.4\,cm$
Since minimum significant figure is $2$.
