Find the diagonal $ d_1 $ of a rhombus if area $A = 88$ and diagonal $d_2 = 8$.
Answer
$d_1 = 22$
Explanation
To find diagonal $ d1 $ use formula:
$$ A = \dfrac{ d_1 \cdot d_2 }{ 2 } $$After substituting $ A = 88 $ and $ d_2 = 8 $ we have:
$$ 88 = \dfrac{ d_1 \cdot 8 }{ 2 } $$$$ 88 \cdot 2 = d_1 \cdot 8 $$$$ 176 = 8 \cdot d_1 $$$$ d_1 = \dfrac{ 176}{ 8 } $$$$ d_1 = 22 $$This page was created using
