The perimeter = 20 and AC = 8

Now as it is not mentioned which sides are equal of the isosceles triangle ABC,

We have two possible situations.

1)

If AC is the base

In that case AB = BC

Now AC = 8, AB = x , BC = x

So x + x + 8 = 20

2x + 8 = 20

2x = 12

x = 6

AB = BC = 6

2)

IF AC is not the base,

Then

AC = BC or AC = AB

So BC = 8 or AB = 8

If AB = AC = 8

Then

BC + 8 + 8 = 20

BC = 4

So there are two possible lengths of BC

Either it is BC = 8 or BC = 6 or BC = 4

The figure is attached for your reference.
