Two classrooms are the same size. Each has seating for 28 students.

Question

In one room, each student has a desk and chair that take up 9 square feet. In the other room, each group of 4 students shares a table and chairs that take up 35 square feet. Each room also has one large table that takes up 15 square feet. Which room has more walking space?

Answer 1

To solve this, you need to determine how much space is occupied by the students and desks in each room.

 

Room 1:

28 students, each using 9 ft² of space for their desk and chair: 28*9 = 252 ft²

one 15 ft² table

----

total = 267 ft²

 

Room 2:

28 students, every 4 of them using 35 ft²: 28/4 = 7 groups * 35 = 245 ft²

one 15 ft² table

---

total = 260 ft²

 

Which room has more space left over?
