The answer is 2.5 because the scale factor is 6/3 so you divide 5 by 2 to get 2.5 as the length of DE

The length of DE is 2.5 units

What is similarity?

Similar figures are two figures having the same shape

Given:

ΔABC and ΔDEF are similar.

then,

AB/ DE = BC/ EF = AC/ DF

Now, AB = AC = 5 units, BC=  6 units

AB/DE = BC/ EF

5 / DE = 6/ 3

15= 6 DE

DE = 5/2 = 2.5

Hence, the value of DE is 2.5 units.
