What is the average size of the one-bedroom units at a community with three different plans?

To determine the average size of the one-bedroom units in a community with three different plans, you would typically need to have the sizes of each individual plan first. Once you have those figures, you can calculate the average by adding the sizes of the three units and then dividing that sum by three.

In this scenario, the correct choice indicates that the average size of the one-bedroom units is 817 square feet. This choice suggests that when the sizes of the different plans are totaled and divided by three, the resulting average aligns precisely with this figure.

When assessing the average, it's essential to consider that the number you choose should represent a typical size that reflects the options available within that community. The figure of 817 square feet likely reflects a well-calculated average derived from the sizes listed for the three plans.

The other options may represent sizes of specific plans, but they do not accurately reflect the overall average when considering a community with multiple one-bedroom unit plans. This highlights the importance of understanding how to compute averages in a property management context, ensuring that the number you present as an average provides potential renters with an accurate expectation of unit size.
