An area reserved for a parking lot is 80 feet long and 77 feet wide. the stalls of the lot are at 90° angles to two one-way aisles. each aisle is 80 feet by 10 feet. the three areas set aside for the parking spaces are congruent rectangles. each parking space will be 19 feet by 8 feet. what is the maximum number of parking spaces that will fit in the lot?

Well the parking spot columns are 80 feet long since they go all the way its length.

there are 2 columns which are 10 feet wide so we can talk out the 20 feet of aisle width. that would mean there is 77 - 20 feet of width for parking spots so 57 feet

the spots are 8 feet wide apiece and their width is parallel to the length of overall lot so there is up to 80 feet. So how many times does 8 feet fit into 80 feet. 10 times. So so we can have 10 spots for each row of spots.

each spot is 19 feet long and there are 3 rows of spots so 19 * 3 = 57. So they fit exactly 3

so we have 3 rows by 10 columns.
3*10 = 30 apots
