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
                      |
