What is the unit used to express the area of the slab in the given calculation?

Explanation:
Area is expressed in square units, because you obtain it by multiplying length by width. If the slab’s dimensions are given in feet, you multiply feet by feet, giving square feet (ft^2). That’s why square feet is the appropriate unit here. The other options would only apply if the measurements were in those respective units (centimeters, meters, or inches) after converting all dimensions to the same unit. For example, 8 ft by 10 ft gives 80 ft^2.
