In which function would you use the ranges called Rents and Leases to calculate a value?

The SUMPRODUCT function is utilized to perform calculations involving multiple ranges. It multiplies corresponding components in the specified arrays and then sums those products. This function is particularly useful when you want to calculate totals based on the combination of values from different ranges, such as the Rents and Leases in this case.

Using ranges like Rents and Leases suggests that you are looking to perform some kind of arithmetic across values within those ranges, which is a perfect fit for SUMPRODUCT. For example, if Rents contains rental amounts for various properties and Leases indicates the number of months each property is leased, applying SUMPRODUCT would yield a total income from all properties based on these factors.

In contrast, other functions like AVERAGEIF focus specifically on calculating averages based on certain conditions, CONCATENATE is used to combine text from different cells, and COUNTA counts the number of cells that are not empty. While these functions are valuable in their own contexts, they do not serve the purpose of calculating a value using multiple ranges in the comprehensive manner that SUMPRODUCT does.
