Find the perimeter $ P $ of a rhombus if side $a = \frac{\sqrt{ 5 }}{ 2 }$.
Answer
$P = 2 \sqrt{ 5 }$
Explanation
To find perimeter $ P $ use formula:
$$ P = 4 \cdot a $$After substituting $ a = \frac{\sqrt{ 5 }}{ 2 } $ we have:
$$ P = 4 \cdot \frac{\sqrt{ 5 }}{ 2 } $$ $$ P = 2 \sqrt{ 5 } $$This page was created using
