\(\frac{81\times51\times14}{102\times54\times35}\)
\(=\frac{\left(27\times3\right)\times5\times\left(2\times7\right)}{\left(51\times2\right)\times\left(2\times27\right)\times\left(5\times7\right)}\)
=> Tới đây, ta xem các tử số và mẫu số, rồi rút gọn chúng.
\(=\frac{3}{2\times5}\)
\(=\frac{3}{10}\)

Gọi chiều rộng của hình chữ nhật là \(a\left(cm\right)\).
Chiều dài của hình chữ nhật là: \(\frac{3}{2}\times a\left(cm\right)\).
Diện tích của hình chữ nhật là: \(\frac{3}{2}\times a\times a\left(cm^2\right)\).
Ta có: \(\frac{3}{2}\times a\times a=726\)
\(\Leftrightarrow a\times a=484\)
Có \(484=22\times22\)do đó \(a=22\).
Chiều dài hình chữ nhật là:
\(22\times\frac{3}{2}=33\left(cm\right)\)
Chu vi hình chữ nhật đó là:
\(\left(33+22\right)\times2=110\left(cm\right)\)
