Using each of the following scales, find the dimensions in a blueprint of an 8ft-by-12ft room.

1. 1 in.:2ft

2. 1 in.:4ft

• Algebra -

1.

1 in = 2 ft Divide both sides with 2

0.5 in = 1 ft

0.5 * 8 = 4 in

0.5 * 12 = 6 in

4 in by 6 in

2.

1 in = 4 ft Divide both sides with 4

0.25 in = 1 ft

0.25 * 8 = 2 in

0.25 * 12 = 3 in

2 in by 3 in

I don't get this.
