The regular polygon will be in the form below:
USing the formula
[tex]\text{Area}=\frac{1}{2}\text{nsr}[/tex]n is the number of sides=7, s is the length of sides and r is the apothem
The length of each of the sides of the heptagon is
[tex]\frac{63}{7}=9\text{inches}[/tex]Now we have all the parameters to solve for the area
[tex]\begin{gathered} \text{Area}=\frac{1}{2}\times7\times9\times8 \\ =252in^2 \end{gathered}[/tex]
