The approximate length of the apothem is mathematically given as,
a=1.5cm, Option C is correct
What is the approximate length of the apothem?
Question Parameters:
the pentagon below has an area of 8.3 square.
Generally, the equation for the length of apothem is mathematically given as
[tex]la=\frac{s}{2Tan(\frac{180}{n})}[/tex]
Therefore
[tex]a=\frac{2.2}{2\ tan(\frac{180}{5})}\\\\a=\frac{2.2}{2\ tan(36)}[/tex]
a=1.51cm
In conclusion, the apothem length is
a=1.51cm
