A rectangular swimming pool has a length of 20 feet and a width of 12 feet. If a safety rope is to be placed around the perimeter of the pool, how much rope is needed?

✓ Correct Answer: Option C

The perimeter of a rectangle is calculated by P = 2(length + width). So, P = 2(20 + 12) = 2(32) = 64 feet. Therefore, 64 feet of rope is needed.
