Question

Find the area of the regular polygon

Answer 1

$area = 44.0467 \: cm {}^{2}$

step by step explanation

● area of regular polygon Formulas ,

⟹$a = \frac{l^{2}n}{4tan(\frac{\pi }{n)}}$

● now finding the area of regular polygon,

⟹$\frac{4 {}^{2} \times 8 }{ 4 \: tan \: \binom{180}{5} }$

⟹$a = \frac{128}{4 \times 0.7265}$

⟹$a = 44.0467 \: cm {}^{2}$
