Answer:

21 units

Step-by-step explanation:

[tex] \triangle ABC\sim \triangle DEF... (given) [/tex]

[tex]\huge \therefore \frac{AB}{DE} =\frac{BC}{EF}.. (csst) [/tex]

[tex] \huge \therefore \frac{8.4}{x} =\frac{10}{25} [/tex]

[tex] \huge \therefore x=\frac{25\times 8.4}{10} [/tex]

[tex] \huge \therefore x=\frac{210}{10} [/tex]

[tex]\huge \therefore x=21 [/tex]

Hence, length of DE = 21 units
