Step-by-step explanation:
So as the usual we can see that
Ab=9 and cd=9
And we can get bc by
ration reading 1
So AB:BC=1:3
SO we said that AB is 9 so we have to multiply The ratio by 9:9 we can see that the ratio will be AB:CD=9:27 the main thing here is we have got the BC which Is 27
So AD means the sum of all Points
AB+BC+CD=AD
9+27+9=AD
AD=45
