The surface area of a rectangular swimming pool that is 50 feet wide and 100 feet long is?

To determine the surface area of a rectangular swimming pool, you multiply its length by its width. In this case, the pool is 50 feet wide and 100 feet long.

Calculating the surface area involves the formula:

Surface Area = Length × Width.

Substituting the given dimensions into this formula:

Surface Area = 100 feet × 50 feet = 5000 square feet.

This result confirms that the correct option is indeed 5000 square feet, which represents the total area of the pool's surface, providing essential information for maintenance, such as water treatment and chemical application. Understanding the surface area is also valuable in contexts such as estimating evaporation rates or planning for safety measures around the pool. The other options do not represent the correct area resulting from the measurements provided.
