Find the perimeter $ P $ of a rectangle if side $a = 12$ and side $b = 11$.
Answer
$P = 46$
Explanation
To find perimeter $ P $ use formula:
$$ P = 2 a + 2 b $$After substituting $ a = 12 $ and $ b = 11 $ we have:
$$ P = 2 \cdot 12 + 2 \cdot 11 $$ $$ P = 24 + 22 $$ $$ P = 46 $$This page was created using
