Find the area $ A $ of a rhombus if side $a = \frac{ 31 }{ 10 }$ and height $h = \frac{ 39 }{ 10 }$.
Answer
$A = \frac{ 1209 }{ 100 }$
Explanation
To find area $ A $ use formula:
$$ A = a \cdot h $$After substituting $ a = \frac{ 31 }{ 10 } $ and $ h = \frac{ 39 }{ 10 } $ we have:
$$ A = \frac{ 31 }{ 10 } \cdot \frac{ 39 }{ 10 } $$$$ A = \frac{ 31 }{ 10 } \cdot \frac{ 39 }{ 10 } $$$$ A = \frac{ 1209 }{ 100 } $$This page was created using
