we know that

If two figures are similar, then the ratio of its corresponding sides is proportional and its corresponding angles are congruent

In this problem

$\frac{20}{14}=\frac{x}{6}$

solve for x

$x=\frac{20}{14}(6)$

$x=\frac{120}{14}\ units$

simplify

$x=\frac{60}{7}\ units$

convert to mixed number

$x=\frac{60}{7}\ units=\frac{56}{7}+\frac{4}{7}=8\frac{4}{7}\ units$
