Find the perimeter $ P $ of a rectangle if side $a = 3$ and side $b = 3 \sqrt{ 2 }$.
Answer
$P = 14.4853$
Explanation
To find perimeter $ P $ use formula:
$$ P = 2 a + 2 b $$After substituting $ a = 3 $ and $ b = 3 \sqrt{ 2 } $ we have:
$$ P = 2 \cdot 3 + 2 \cdot 3 \sqrt{ 2 } $$ $$ P = 6 + 6 \sqrt{ 2 } $$ $$ P = 14.4853 $$This page was created using
