Question
Find the side $ b $ of a rectangle if side $a = 18\, \text{cm}$ and area $A = 576\, \text{cm}$.
Answer
$32$
Explanation
To find side $ b $ use formula:
$$ A = a \cdot b $$After substituting $A = 576\, \text{cm}$ and $a = 18\, \text{cm}$ we have:
$$ 576\, \text{cm} = 18\, \text{cm} \cdot b $$$$ b = \dfrac{ 576\, \text{cm} }{ 18\, \text{cm} } $$$$ b = 32 $$This page was created using
