If you're just focusing on the boundary, it's the circle . Parameterize it by taking and , with . Then reduces to a univariate function :
Then you can find any extrema on the boundary by checking the critical points of .
Answer: domain: (-oo,oo) range: (0,oo)
the area= 12.25 one side =: 1.5 then the dimension then answer is 13.75
