Question

Consider the blueprint (scale drawing) of a living room in a house. The size of the longest wall in the house is 16 ft.

A room has wall lengths of one-fourth foot, StartFraction 1 over 12 EndFraction feet, one-sixth foot, and one-third foot.

What can be concluded about the information on the blueprint of the living room? Check all that apply.
A. Scale factor = StartFraction scale drawing wall over original wall EndFraction = StartFraction one-third over 16 EndFraction = StartFraction 1 over 48 EndFraction
B. Scale factor = StartFraction scale drawing wall over original wall EndFraction = StartFraction 16 over one-third EndFraction = StartFraction 48 EndFraction
C. Multiply each length of the scale drawing by the scale factor to find the lengths of the walls.
D. Divide each length of the scale drawing by the scale factor to find the lengths of the walls.
E. Add the scale factor to each length of the scale drawing to find the lengths of the walls.

Answer 1

A. Scale factor = StartFraction scale drawing wall over original wall EndFraction = StartFraction one-third over 16 EndFraction = StartFraction 1 over 48 EndFraction
C. Multiply each length of the scale drawing by the scale factor to find the lengths of the walls.
