Question
Find the area $ A $ of a rhombus if diagonal $d_1 = 81\, \text{cm}$ and diagonal $d_2 = 37.5\, \text{cm}$.
Answer
$1518.75\, \text{cm}^2$
Explanation
To find area $ A $ use formula:
$$ A = \dfrac{ d_1 \cdot d_2 }{ 2 } $$After substituting $d_1 = 81\, \text{cm}$ and $d_2 = 37.5\, \text{cm}$ we have:
$$ A = \dfrac{ 81\, \text{cm} \cdot 37.5\, \text{cm} }{ 2 }$$$$ A = \dfrac{ 3037.5\, \text{cm}^2 }{ 2 } $$$$ A = 1518.75\, \text{cm}^2 $$This page was created using
