STEP 1: find side $ a $
To find side $ a $ use formula:
$$ d = 2 \cdot a $$After substituting $ d = 229 $ we have:
$$ 229 = 2 \cdot a $$ $$ a = \dfrac{ 229 }{ 2 } $$ $$ a = \frac{ 229 }{ 2 } $$STEP 2: find diagonal $ s $
To find diagonal $ s $ use formula:
$$ s = \sqrt{ 3 } \cdot a $$After substituting $ a = \frac{ 229 }{ 2 } $ we have:
$$ s = \sqrt{ 3 } \cdot \frac{ 229 }{ 2 } $$ $$ s = \frac{ 229 \sqrt{ 3}}{ 2 } $$
