Find the area $ A $ of a hexagon if side $a = \frac{ 19 }{ 5 }$.
Answer
$A = \frac{ 1083 \sqrt{ 3}}{ 50 }$
Explanation
To find area $ A $ use formula:
$$ A = \dfrac{ 3 \sqrt{ 3 } \cdot a^2 }{ 2 } $$After substituting $ a = \frac{ 19 }{ 5 } $ we have:
$$ A = \dfrac{ 3 \sqrt{ 3 } \cdot \left(\frac{ 19 }{ 5 }\right)^2 }{ 2 } $$ $$ A = \dfrac{ 3 \sqrt{ 3 } \cdot \frac{ 361 }{ 25 } }{ 2 }$$ $$ A = \dfrac{ \frac{ 1083 \sqrt{ 3}}{ 25 } }{ 2 }$$ $$ A = \frac{ 1083 \sqrt{ 3}}{ 50 } $$This page was created using
