Recall that the dilation factor for the scale is 100, then if a room is 0.1 by 0.12 in the blueprint, the room is in fact 10 ft by 12 ft in real life.
The person would need to have baseboard of the size of the perimeter of the room:
2 * 10 + 2 * 12 = 20 + 24 = 44 ft of baseboard. This agrees with the first answer option.
