I'm assuming you mean that it has crashed inside the forest, and the probablity that it has crashed in the lake. 

This is a case of geometric probability.

The total area of the entire forest is 4.5*9.

The area of the lake is 3*2.5

The probability therefore is \(\frac{2.5*3}{4.5*9}=\frac{5}{27}\)
