Step-by-step explanation:

we know that

The area of the regular polygon is equal to

[tex]A=\frac{1}{2}Pa[/tex]

where

P is the perimeter of the regular polygon

a is the apothem

Find the perimeter P

[tex]P=8(7)=56\ units[/tex]

Find the area

[tex]A=\frac{1}{2}(56)(10.49)=293.72\ units^{2}[/tex]
