let x represent the blueprint representation of the actual living room size.
you know that 48 millimeters represents 9 meters.
if you take 48 millimeters and divide it by 9 meters, you get 5 and 1/3 millimeters on the blueprint for every meter in real life.
since the actual length of the living room is 6 meters, then multiply that by (5 and 1/3) to get (5 + 1/3) * 6 = 5 * 6 + 1/3 * 6.
this results in 30 + 2 = 32 millimeters.
32 millimeters on the blueprint represents an actual length of 6 meters.
the ratio of blueprint to actual should be preserved.
48/9 = 32/6
cross multiply to get 48 * 6 = 9 * 32.
simplify to get 288 = 288, confirming the ratios are equivalent.
