It looks like TPC is greatly underutilizing its available space. Create a query that returns the BuildingName field and a second calculated field named $\%$Unused. This second field should calculate the percent of each building's space that is not used. Format the values in this second field as a percent with no decimal places. Sort in ascending sequence by BuildingName. You can calculate the total space available in each building by multiplying its length by its width. Save this query as Query$4$
