Question
Find the area $ A $ of a rhombus if diagonal $d_1 = 18\, \text{cm}$ and diagonal $d_2 = 16\, \text{cm}$.
Answer
$144\, \text{cm}^2$
Explanation
To find area $ A $ use formula:
$$ A = \dfrac{ d_1 \cdot d_2 }{ 2 } $$After substituting $d_1 = 18\, \text{cm}$ and $d_2 = 16\, \text{cm}$ we have:
$$ A = \dfrac{ 18\, \text{cm} \cdot 16\, \text{cm} }{ 2 }$$$$ A = \dfrac{ 288\, \text{cm}^2 }{ 2 } $$$$ A = 144\, \text{cm}^2 $$This page was created using
