What is the square footage of a wall that is 8 feet long by 12 feet high?

To determine the square footage of a wall, you multiply its length by its height. In this case, the wall is 8 feet long and 12 feet high. Performing the calculation:

8 feet (length) × 12 feet (height) = 96 square feet.

This result reflects the total area of the wall's surface, making the correct answer 96 square feet. Understanding this formula is essential in masonry and construction, as it allows for accurate measurements needed for materials and estimating costs.
