Find the area $ A $ of a rhombus if side $a = 338$ and angle $\alpha = \frac{ 73 }{ 2 }^o$.
Answer
$A = 67954.9344$
Explanation
To find area $ A $ use formula:
$$ A = \dfrac{ a \cdot a \cdot \sin( \alpha ) }{ 1 } $$After substituting $ a = 338 $ , $ a = 338 $ and $ \alpha = \frac{ 73 }{ 2 }^o $ we have:
$$ A = \dfrac{ 338 \cdot 338 \cdot \sin( \frac{ 73 }{ 2 }^o ) }{ 1 } $$ $$ A = \dfrac{ 338 \cdot 338 \cdot 0.5948 }{ 1 } $$ $$ A = \dfrac{ 114244 \cdot 0.5948 }{ 1 } $$ $$ A = \dfrac{ 67954.9344 }{ 1 } $$ $$ A = 67954.9344 $$This page was created using
