Areas from Origin

A point in the integer plane is defined by a pair of integers $(x, y)$ : first the x-axis coordinate, then the y-axis coordinate, as usual. Such a point defines an axis-parallel rectangle with respect to the origin of coordinates, namely $(0, 0)$ . The other two corners are, clearly, $(0, y)$ and $(x, 0)$ . What is the area of this rectangle? Write a function $area(x,y)$ that receives two integers $x$ and $y$ and returns the area of the rectangle specified in this manner.

An approximate drawing of the public test cases, with points $p: (5,3)$ and $q: (-1, -1)$ could be:

                  |
                  3 -- - -- - -- - -- - -- p
                  |                        |
                  2                        |
                  |                        |
                  1                        |
                  |                        |
- -3 - -2 - -1 -- 0 -- 1 -- 2 -- 3 -- 4 -- 5 --
             |    |
             q - -1
                  |
                 -2
                  |
