Find the area $ A $ of a rhombus if diagonal $d_1 = 10$ and diagonal $d_2 = 8$.
Answer
$A = 40$
Explanation
To find area $ A $ use formula:
$$ A = \dfrac{ d_1 \cdot d_2 }{ 2 } $$After substituting $ d_1 = 10 $ and $ d_2 = 8 $ we have:
$$ A = \dfrac{ 10 \cdot 8 }{ 2 }$$$$ A = \dfrac{ 80 }{ 2 } $$$$ A = 40 $$This page was created using
