How many two-bedroom apartment units are calculated for a building with 4 floors and 7 units per floor?

To determine the total number of two-bedroom apartment units in a building with 4 floors and 7 units per floor, you multiply the number of floors by the number of units on each floor.

In this case, the calculation is:

Number of floors (4) multiplied by the number of units per floor (7):

4 floors × 7 units/floor = 28 units.

This shows that the total number of apartment units in the building is indeed 28. Therefore, the two-bedroom apartment units amount to 28, confirming that this is the correct answer.
