Find the diagonal $ d_2 $ of a rhombus if area $A = 600$ and diagonal $d_1 = 40$.
Answer
$d_2 = 30$
Explanation
To find diagonal $ d2 $ use formula:
$$ A = \dfrac{ d_1 \cdot d_2 }{ 2 } $$After substituting $ A = 600 $ and $ d_1 = 40 $ we have:
$$ 600 = \dfrac{ 40 \cdot d_2 }{ 2 } $$$$ 600 \cdot 2 = 40 \cdot d_2 $$$$ 1200 = 40 \cdot d_2 $$$$ d_2 = \dfrac{ 1200 }{ 40 } $$$$ d_2 = 30 $$This page was created using
