Find the area $ A $ of a rhombus if diagonal $d_1 = 9$ and diagonal $d_2 = 5$.
Answer
$A = \frac{ 45 }{ 2 }$
Explanation
To find area $ A $ use formula:
$$ A = \dfrac{ d_1 \cdot d_2 }{ 2 } $$After substituting $ d_1 = 9 $ and $ d_2 = 5 $ we have:
$$ A = \dfrac{ 9 \cdot 5 }{ 2 }$$$$ A = \dfrac{ 45 }{ 2 } $$$$ A = \frac{ 45 }{ 2 } $$This page was created using
