What is the area bounded by the region $$|x+y|+|x-y|=4$$.Where $$x,y$$ are real numbers.

Taking four pairs of sign for $(x, y)$ and considering magnitude of $x$ vs. that of $y$ in each of the four cases, you would get a square as the bounded region. It should then be a matter of moments to compute the area.
