Question
Find the side $ a $ of a rectangle if side $b = 4\, \text{cm}$ and area $A = 100\, \text{cm}$.
Answer
$7.9577$
Explanation
To find side $ a $ use formula:
$$ A = a \cdot b $$After substituting $A = 100\, \text{cm}$ and $b = 4\, \text{cm}$ we have:
$$ 100\, \text{cm} = 4\, \text{cm} \cdot a $$$$ a = \dfrac{ 100\, \text{cm}}{ 4\, \text{cm} } $$$$ a \approx 7.9577 $$This page was created using
