Total Fencing Cost

Alice wants to fence her rectangular garden. She needs to know how much it will cost to fence the entire perimeter. The garden has a length l and a width w (in meters), and the fencing costs c dollars per meter. The total cost is calculated by computing the perimeter of the rectangle and then multiplying it by the cost per meter.

Mathematically, the perimeter P is given by:

\( P = 2 \times (l + w) \)

and the total fencing cost is:

\( \text{Cost} = P \times c = 2 \times (l + w) \times c \)

inputFormat

The input consists of a single line containing three space-separated integers:

• l (the length of the garden in meters),
• w (the width of the garden in meters), and
• c (the cost per meter of the fencing in dollars).

outputFormat

Output a single integer representing the total cost of fencing the garden in dollars.
