Explanation:

Step1: Recall area formula

The area formula for a rectangle is $A = l\times w$, where $l$ is the length and $w$ is the width.

Step2: Substitute values

Given $l = 4.4$ cm and $w = 3.1$ cm, then $A=4.4\times3.1$.

Step3: Calculate result

$4.4\times3.1 = 13.64$ cm².

Step4: Round to 2 significant - figures

Rounding 13.64 to 2 significant - figures gives 14 cm².

Answer:

14
