AD/ 4.5 = 4/5
AD = 4(4.5) / 5
AD = 3.6


answer
AD = 3.6

Here BD is the angle bisector , so we have

∠ABD =∠CBD

now comparing the ratios , we have

[tex] \frac{AD}{4.5} = \frac{4}{5} [/tex]

Now we can multiply 4.5 on the right hand side , to get the value of AD,

[tex] AD = \frac{4}{5} * 4.5 [/tex]

So this gives AD =3.6
