Find the side $ a $ of an equilateral triangle if perimeter $P = \frac{ 33 }{ 10 }$.
Answer
$a = \frac{ 11 }{ 10 }$
Explanation
To find side $ a $ use formula:
$$ P = 3 \cdot a $$After substituting $ P = \frac{ 33 }{ 10 } $ we have:
$$ \frac{ 33 }{ 10 } = 3 \cdot a $$ $$ a = \dfrac{ \frac{ 33 }{ 10 } }{ 3 } $$ $$ a = \frac{ 11 }{ 10 } $$This page was created using
