Final answer:
The area of a living room with dimensions x * x is represented by x² square units. This is calculated using the area formula length x width, where both length and width are represented by 'x'.
Step-by-step explanation:
In Mathematics, to calculate the area of a shape, namely a rectangle or a square, which can represent a living room, we typically multiply the length and the width. In this case, you've indicated that the living room has dimensions of x * x, which suggests it's a square (since both dimensions are the same).
The formula for the area of a square is length x width, which in this case is x * x or x². So, the area of the living room would be x² square units, where 'x' represents the length of one side.
