Let B is the point of Sharks
Let D is the point of Dophines
Let P is the point of penguins

AB//PF
In triangle ABD and DPF we have
- ∠BAD=∠PFD(Alternate angles)
- ∠ADB=∠PDF(Vertically opposite angles)

Therefore, using the similarity property, we have:
=
So the distance between the penguins and the fish tanks is 81 ft
