Answer:
Length of width in the blueprint is 3.5 inches
Step-by-step explanation:
We have given dimensions of a room as 18ft long by 18ft wide.
To represent this room dimensions in a blueprint, the dimensions of room is re-scaled as :
By length it is represented as 3.5 inches long
So we can find scaling factor here as:
Scaling factor = 3.5 / 216 (Since 18 ft = 216 inches)
Scaling factor = 7/432
Now, to get width of room in the blueprint, we multiply actual length of width by the scaling factor.
Length of width in blueprint = scaling factor * width(in inches)
Length of width in blueprint = (7/432 ) * 216 , (Since 18ft = 216 inches)
Length of width in blueprint = 3.5 inches
So we get length of width in blueprint is 3.5 inches
