Use this rule: \(\frac{a}{b} \times \frac{c}{d}=\frac{ac}{bd}\).
\[54000\times \frac{21\times 21}{20\times 20}\]
Simplify \(21\times 21\) to \(441\).
\[54000\times \frac{441}{20\times 20}\]
Simplify \(20\times 20\) to \(400\).
\[54000\times \frac{441}{400}\]
Use this rule: \(a \times \frac{b}{c}=\frac{ab}{c}\).
\[\frac{54000\times 441}{400}\]
Simplify \(54000\times 441\) to \(23814000\).
\[\frac{23814000}{400}\]
Simplify.
