A blueprint shows a reduction of a room using a scale factor of 1/50. In the blueprint, the rooms length is 8 in., and its width is 6 in. Find the perimeter of the room?

Answer:

1/50 means that actual room is 50 times bigger than on blueprint.
Perimeter on blueprint:
2*(8 + 6) = 2 * 14 = 28in.
Perimeter of room:
28*50=1400in.
