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

dilation scale factor 2: starting with δabc, draw the dilation image of the triangle with a center at the origin and a scale factor of two. notice that every coordinate of the original triangle has been multiplied by the scale factor (x2). dilation with scale factor 2, multiply by 2.

answer is because 4×10=40

and 98×4= is 392

40,392
