Answer 1

$\frac{x}{20}$ =$\frac{35}{25}$ =$\frac{y}{40} [/tex        [tex] \frac{x}{20}$ = $\frac{7}{5}$-------- x = 28 cm
       $\frac{y}{40}$ = $\frac{7}{5}$----------y = 56 cm

Answer 2

.
$\frac{x}{20} = \frac{35}{25} = \frac{y}{40} \\ \\ \frac{x}{20} = \frac{35:5}{25:5} \\ \\ \frac{x}{20} = \frac{7}{5} \\ \\ 5x=140 \\ x=140\div5 \\ x=28 \\ \\ \\ \frac{y}{40} = \frac{7}{5} \\ \\ 5y=280 \\ \\ y=280\div5 \\ y=56$
