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


ANSWER

$$4.431cm$$


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).
