Find the diagonal $ d_2 $ of a rhombus if area $A = 300$ and diagonal $d_1 = 15$.
Answer
$d_2 = 40$
Explanation
To find diagonal $ d2 $ use formula:
$$ A = \dfrac{ d_1 \cdot d_2 }{ 2 } $$After substituting $ A = 300 $ and $ d_1 = 15 $ we have:
$$ 300 = \dfrac{ 15 \cdot d_2 }{ 2 } $$$$ 300 \cdot 2 = 15 \cdot d_2 $$$$ 600 = 15 \cdot d_2 $$$$ d_2 = \dfrac{ 600 }{ 15 } $$$$ d_2 = 40 $$This page was created using
