The dimensions would be 2 by 2.

We are fencing in 3 sides. The southern side is twice as expensive as the other two sides; the eastern and western sides together equal as much as the southern side. We have $80 to spend.

20x+10x+10x = 80

40x = 80

x = 2

This means that we can have 2 feet on all sides, for a total of 10 (2) + 10 (2) + 20 (2) = 80.
