189 Un rettangolo ha un lato quadruplo dell'al- tro e la somma delle lunghezze dei due lati è 20 cm . Disegna il rettangolo nelle misure reali. Un rettangolo ha il perimetro di 30 cm e i lati sono in rapporto \( 2: 3 \). Calcola la lunghezza dei suoi lati.

Find the product: \( \begin{array}{ll}\text { (a) } \frac{2}{3} \times 12 & \text { (b) } \frac{3}{8} \times 15 \\ \text { Find the value: }\end{array} \)

\( \frac{\left(\frac{3}{7} \text { ของ } 35\right)+\frac{2}{3}}{\left(\frac{6}{10} \div \frac{2}{5}\right) \times \frac{8}{12}}=\square \)
