# if $L=2.331 cm$, $B = 2.1 cm$, then L+B=

$4.431cm$

##### SOLUTION
Step 1
$L = 2.331 cm = 2.33$ (corrected to two decimal places) and $B = 2.1 cm$
Step 2
$L + B = 2.33 + 2.1 = 4.43cm. = 4.4cm$
(by the rule of addition the sum is expressed in minimum decimal places of terms in addition).

You're just one step away
