The largest possible area of the forest is 2500 km^2
How to determine the largest area?
The perimeter is given as:
P = 200 km
The shape that will give the largest possible area for the forest is a square, and the area is calculated as:
A = (P/4)^2
This gives
A = (200/4)^2
Evaluate
A = 2500 km^2
Hence, the largest possible area of the forest is 2500 km^2
