Find the diagonal $ d_2 $ of a rhombus if area $A = 48$ and diagonal $d_1 = 12$.
Answer
$d_2 = 8$
Explanation
To find diagonal $ d2 $ use formula:
$$ A = \dfrac{ d_1 \cdot d_2 }{ 2 } $$After substituting $ A = 48 $ and $ d_1 = 12 $ we have:
$$ 48 = \dfrac{ 12 \cdot d_2 }{ 2 } $$$$ 48 \cdot 2 = 12 \cdot d_2 $$$$ 96 = 12 \cdot d_2 $$$$ d_2 = \dfrac{ 96 }{ 12 } $$$$ d_2 = 8 $$This page was created using
