In blueprints an architects firm drew everything 1/24 of the actual size the windows will actually measure 4feet by 6 feet and the doors measure 12 feet by 8 feet what are the dimensions of the windows and doors

To apply a scale to a measure, you have to follow this rule:

Real measure x Scale = Scaled measure

So the drawings will have:

4 x 1/24 = 0'167 feet

6 x 1/24 = 0'25 feet

Windows: 0'167 by 0'25 feet

12 x 1/24 = 0'50 feet

8 x 1/24 = 0'33 feet

Doors: 0'33 by 0'50 feet
