Find the perimeter $ P $ of a rectangle if side $a = \frac{ 7 }{ 2 }$ and side $b = \frac{ 5 }{ 2 }$.
Answer
$P = 12$
Explanation
To find perimeter $ P $ use formula:
$$ P = 2 a + 2 b $$After substituting $ a = \frac{ 7 }{ 2 } $ and $ b = \frac{ 5 }{ 2 } $ we have:
$$ P = 2 \cdot \frac{ 7 }{ 2 } + 2 \cdot \frac{ 5 }{ 2 } $$ $$ P = 7 + 5 $$ $$ P = 12 $$This page was created using
