Hi, My name is Teresa and I am a student, I need help with a math word problem.

On the blueprint, the scale indicates that 2 cm represents 5 ft. What are the actual dimensions of a room that is 4.8 cm by 6 cm on the blueprint?

This is a middle level question.

Thank you very much!


Hi Teresa,

If 2 cm represents 5 ft then 1 cm represents 2.5 ft.

In the blueprint the width of a doorway is 1.1 cm. Since each cm represents 2.5 ft the actual width of the doorway is

1.1 2.5 = 2.75 feet which is 33 inches.

What are the actual dimensions of the room?
