Find the area $ A $ of a rhombus if diagonal $d_1 = \frac{ 4 }{ 5 }$ and diagonal $d_2 = \frac{ 7 }{ 2 }$.
Answer
$A = \frac{ 7 }{ 5 }$
Explanation
To find area $ A $ use formula:
$$ A = \dfrac{ d_1 \cdot d_2 }{ 2 } $$After substituting $ d_1 = \frac{ 4 }{ 5 } $ and $ d_2 = \frac{ 7 }{ 2 } $ we have:
$$ A = \dfrac{ \frac{ 4 }{ 5 } \cdot \frac{ 7 }{ 2 } }{ 2 }$$$$ A = \dfrac{ \frac{ 14 }{ 5 } }{ 2 } $$$$ A = \frac{ 7 }{ 5 } $$This page was created using
