Find the area $ A $ of a hexagon if side $a = 5$.
Answer
$A = \frac{ 75 \sqrt{ 3}}{ 2 }$
Explanation
To find area $ A $ use formula:
$$ A = \dfrac{ 3 \sqrt{ 3 } \cdot a^2 }{ 2 } $$After substituting $ a = 5 $ we have:
$$ A = \dfrac{ 3 \sqrt{ 3 } \cdot 5^2 }{ 2 } $$ $$ A = \dfrac{ 3 \sqrt{ 3 } \cdot 25 }{ 2 }$$ $$ A = \dfrac{ 75 \sqrt{ 3 } }{ 2 }$$ $$ A = \frac{ 75 \sqrt{ 3}}{ 2 } $$This page was created using
