Question

the scale in a drawing is 2 in.:8 ft. On the drawing, a rolm is 3 inches long. What is the length in feet of the actual room?

Answer 1

I believe the length of the actual room would be 12 ft.

To figure this out, first find how many feet one inch represents.
8/2, or 4 feet. <
Then, we have 3 inches. Since 1 inch represents 4 feet, 3 inches must represent 12 feet, as 3*4=12.

Hope this helped! :)

Answer 2

2 in: 8 ft simplifies to 1 in: 4 ft which is just generally easier to work with.

1 in: 4 ft = 3 in: x ft

x ft= 4*3 = 12

The length of the actual room is 12 feet.

Hope this helps!
