<em>Answer:</em>
<em>332 square inch</em>
<em>Step-by-step explanation:</em>
<em>Solving for an area of a regular octagon, we can make use of the formula shown below:
</em>
<em>
</em>
<em>Area = 1/2 * apothem*perimeter
</em>
<em>
</em>
<em>In this problem, the following values were given such as:
</em>
<em>Apothem = 10 inches
</em>
<em>Perimeter = 66.3 inches
</em>
<em>
</em>
<em>Solving for the area:
</em>
<em>Area = 1/2*10*66.3
</em>
<em>Area = 331.5 inches²
</em>
<em>
</em>
<em>The answer is 332.</em>
