Find the perimeter $ P $ of a rectangle if side $a = 7$ and side $b = 7$.
Answer
$P = 28$
Explanation
To find perimeter $ P $ use formula:
$$ P = 2 a + 2 b $$After substituting $ a = 7 $ and $ b = 7 $ we have:
$$ P = 2 \cdot 7 + 2 \cdot 7 $$ $$ P = 14 + 14 $$ $$ P = 28 $$This page was created using
