Answer:
First quadrant.
Step-by-step explanation:
Quadrants:
In the first quadrant, both x and y are positive, that is, x > 0, y > 0.
In the second quadrant, x is negative while y is positive, that is, x < 0, y > 0.
In the third quadrant, both x and y are negative, that is, x < 0, y < 0
In the fourth quadrant, x is positive while y is negative, that is, x > 0, y < 0
In this question:
Both the height of a building, which is x, and the number of rooms in the building, which is x, have to be positive numbers, and thus, the point (x,y) lies on the first quadrant.
