Find the perimeter $ P $ of a rectangle if side $a = 11$ and side $b = 5$.
Answer
$P = 32$
Explanation
To find perimeter $ P $ use formula:
$$ P = 2 a + 2 b $$After substituting $ a = 11 $ and $ b = 5 $ we have:
$$ P = 2 \cdot 11 + 2 \cdot 5 $$ $$ P = 22 + 10 $$ $$ P = 32 $$This page was created using
