What is the calculation for the total number of bedrooms when there are 28 two-bedroom units?

To determine the total number of bedrooms for 28 two-bedroom units, you take the number of units and multiply it by the number of bedrooms in each unit. Since each unit has two bedrooms, the calculation would be 28 units multiplied by 2 bedrooms per unit.

So, the calculation is as follows:

28 units x 2 bedrooms/unit = 56 bedrooms.

This straightforward multiplication clearly shows that the total number of bedrooms across all units is indeed 56. This is why the answer that states 56 rooms calculated by 28 units is correct.
