Find the perimeter $ P $ of an equilateral triangle if side $a = \frac{ 5 }{ 2 }$.
Answer
$P = \frac{ 15 }{ 2 }$
Explanation
To find perimeter $ P $ use formula:
$$ P = 3 \cdot a $$After substituting $ a = \frac{ 5 }{ 2 } $ we have:
$$ P = 3 \cdot \frac{ 5 }{ 2 } $$ $$ P = \frac{ 15 }{ 2 } $$This page was created using
