Mona made a scale drawing of an apartment. The scale of the drawing was 1 inch : 3 feet. A rug by the door is 6 feet long in real life. How long is the rug in the drawing?

___inches

Since the scale of the drawing is 1 inch : 3 feet, we can set up the proportion:

1 inch / 3 feet = x inches / 6 feet

Cross multiplying, we get:

3x = 6

Dividing both sides by 3, we find:

x = 2

Therefore, the rug is 2 inches long in the drawing.
