Find the perimeter $ P $ of a rectangle if side $a = \frac{ 5 }{ 2 }$ and side $b = 10$.
Answer
$P = 25$
Explanation
To find perimeter $ P $ use formula:
$$ P = 2 a + 2 b $$After substituting $ a = \frac{ 5 }{ 2 } $ and $ b = 10 $ we have:
$$ P = 2 \cdot \frac{ 5 }{ 2 } + 2 \cdot 10 $$ $$ P = 5 + 20 $$ $$ P = 25 $$This page was created using
