उत्तर

`bb(4/3)`

Explanation:


From the given figure, we get that

`{:(AD = 3  "units"","  DB = 1  "units"","),(and AB = 4  "units"):}}`   ...(i)

As ∆ABC ∼ ∆ADE, we get

`(AB)/(AD) = (BC)/(DE) = (AC)/(AE)`   ...`[("Ratio of Corresponding"),("sides of similar triangles")]`

∴ `4/3 = (BC)/(DE) = (AC)/(AE)`   ...[From (i)]
