`input()` reads data entered by the user. The result of `input()` is initially a string. `split()` separates one input line into individual values using spaces. `map()` applies the specified conversion to each input value. The `*` operator multiplies numbers. `print()` displays the program result. Print only what the problem statement requires.

**Connection to this task.** The `*` operator multiplies numeric values. In formulas it naturally models repeated contribution, such as price × quantity, speed × time, or side × side. The expression `a * b` shows how this idea is applied to the task data.

For this task, pay special attention to `map(int, input().split())`: it connects the concept above to the concrete computation or program action.

**Focus: “Rectangle Area”.** The same basic mechanism is used in a different context here, so understand the operation itself rather than memorizing a finished line of code.
