Find the area $ A $ of a rhombus if side $a = 2$ and angle $\alpha = 58^o$.
Answer
$A = 3.3922$
Explanation
To find area $ A $ use formula:
$$ A = \dfrac{ a \cdot a \cdot \sin( \alpha ) }{ 1 } $$After substituting $ a = 2 $ , $ a = 2 $ and $ \alpha = 58^o $ we have:
$$ A = \dfrac{ 2 \cdot 2 \cdot \sin( 58^o ) }{ 1 } $$ $$ A = \dfrac{ 2 \cdot 2 \cdot 0.848 }{ 1 } $$ $$ A = \dfrac{ 4 \cdot 0.848 }{ 1 } $$ $$ A = \dfrac{ 3.3922 }{ 1 } $$ $$ A \approx 3.3922 $$This page was created using
