...

Regardless of the approach, always conclude with:

Therefore, the final answer is: $oxed{answer}$. I hope it is correct.

Where [answer] is just the final number or expression that solves the problem.

Problem: Find the area of the region described by $x \ge 0,$ $y \ge 0,$ and
\[100 \{x\} \ge \lfloor x \rfloor + \lfloor y \rfloor.\]Note: For a real number $x,$ $\{x\} = x - \lfloor x \rfloor$ denotes the fractional part of $x.$  For example, $\{2.7\} = 0.7.$
