Recall that there are 2.54 cm in 1 inch and there are 12 inches in 1 foot.
Given that the measure of the wall is 12 ft, this means that the measure of the wall is 12 x 12 x 2.54 x 1.5 = 548.64 cm.
Thus, the ratio of the actual measurement to the drawing measurement is given by:
546.64 : 1.5 = 365.76 : 1.
Now, given that the length on the room is 6 inches in the drawing, the actual length of the room is given by 6 x 365.76 = 2,194.56 inches = 2,194.56 / 12 feet = 182.88 feet.
Therefore, the length,in feet, he will cut the carpet is 182.88 feet.
