21 units

Step-by-step explanation:

$\triangle ABC\sim \triangle DEF... (given)$

$\huge \therefore \frac{AB}{DE} =\frac{BC}{EF}.. (csst)$

$\huge \therefore \frac{8.4}{x} =\frac{10}{25}$

$\huge \therefore x=\frac{25\times 8.4}{10}$

$\huge \therefore x=\frac{210}{10}$

$\huge \therefore x=21$

Hence, length of DE = 21 units
