Question
Find the area $ A $ of a rhombus if side $a = 3.1\, \text{cm}$ and height $h = 3.9\, \text{cm}$.
Answer
$12.09\, \text{cm}^2$
Explanation
To find area $ A $ use formula:
$$ A = a \cdot h $$After substituting $a = 3.1\, \text{cm}$ and $h = 3.9\, \text{cm}$ we have:
$$ A = 3.1\, \text{cm} \cdot 3.9\, \text{cm} $$$$ A = 3.1\, \text{cm} \cdot 3.9\, \text{cm} $$$$ A = 12.09\, \text{cm}^2 $$This page was created using
