The scale of a room in a blueprint is 2 inches : 1 foot. A window in the same blueprint is 12 inches. How long is the actual window?

The window is actually 6 feet long

Step-by-step explanation:

To solve this problem we have to see how to use the scale

2 in : 1ft

We divide the 12 inches that we have by the 2 inches of the scale

12 in / 2 in = 6

Now we multiply the number he gave us by 1ft of the scale

6 * 1ft = 6ft

The window is actually 6 feet long
