Let B is the point of Sharks

Let D is the point of Dophines

Let P is the point of penguins

Let F is the point of Fish tank

From a look at the photo, we can find some special properties that:

AB//PF

In triangle ABD and DPF we have

By AA rule, ABD and DPF are similar to each other

Therefore, using the similarity property, we have:

=

So the distance between the penguins and the fish tanks is 81 ft
