A blueprint of a house has a scale factor of 1in=6ft the living room has a dimension of 18ft by 24ft what are the dimensions on the blueprint of the living room

Question

I have to have two different proportions

Answer 1

If we assume that 18' x 24' represents the length times the width of the living room, then:

 

1/6 = x/18, if we let x = the length

 

and

 

1/6 = y/24 if we let y = the width

 

To find x and y, cross-multiply

 

The first equation becomes:

 

6x = 18

 

x = 3 in.

 

The second equation becomes:

 

6y = 24

 

y = 4 inches

 

The dimensions on the blueprint are 3 in. x 4 in.
