Step-by-step explanation:
The correct definition of merchandise productivity is 1) Net sales divided by the total square feet of retail floor space.
Merchandise productivity measures the efficiency of a retail store in generating sales relative to its retail floor space. It helps assess how much sales a store is able to generate per square foot of space.
For example, if a store has net sales of $500,000 and a total retail floor space of 10,000 square feet, the merchandise productivity would be $50 per square foot ($500,000/10,000 square feet).
