Answer:
B. 2341 square units
Step-by-step explanation:
We can divide the regular octagon into 8 similar isosceles triangles.
The area of the regular octagon then becomes
[tex]Area=8(\frac{1}{2}bh)[/tex]
where [tex]b=22[/tex] units is the base the triangle and [tex]h=26.6[/tex] units is the height of the triangle.
We substitute these values into the formula to get;
[tex]Area=8(\frac{1}{2}\times 22\times26.6)[/tex]
[tex]Area=8\times11\times26.6[/tex]
[tex]Area=2340.8[/tex]
[tex]Area=2341[/tex] to the nearest square unit
