## Homework Statement

Given

[tex] x+y = 6\sqrt2[/tex]

[tex] a + b = 6\sqrt 2 [/tex]

Find minimum value of [tex]\sqrt{x^2 + a^2} + \sqrt{y^2+b^2}[/tex]

**2. The attempt at a solution**

I had plotted the [tex] f(x,y) [/tex] with constant [tex] a ,b[/tex]

And that's all. I don't realize how to do this.

Any comment will be appreciated
