To solve this problem, you can use the proportion:
44 millimeters / 8 meters = 33 millimeters / x meters
Cross-multiplying, we get:
44 millimeters * x meters = 8 meters * 33 millimeters
Solving for x, we find that:
x = (8 meters * 33 millimeters) / 44 millimeters
= (8 * 33) / 44
= 264 / 44
= 6 meters
So the actual length of the living room is 6 meters.
