To determine what percentage the living room represents of the total size of the house, you start by taking the size of the living room (500 square feet) and dividing it by the total size of the house (2,800 square feet).

The calculation is as follows:

1. Divide the size of the living room by the total size of the house:

\[

\frac{500}{2800} = 0.1786

\]

2. To convert this decimal into a percentage, multiply by 100:

\[

0.1786 \times 100 = 17.86\%

\]

This can be rounded to approximately 18%. Therefore, the living room makes up 18% of the total area of the house. It’s important to perform this calculation accurately to understand how different spaces contribute to the overall property size, which can be especially relevant in real estate assessments and when showcasing properties to potential buyers.

The other options represent incorrect calculations or misunderstandings of the percentage formula, as they either misinterpret the numbers or fail to apply the conversion to a percentage correctly.
