Explanation:

A blueprint for a house has a scale of 1:10. A wall in the blueprint is 8in.

Blueprint has a scale ratio of
`(1)/(10)`

As per the scale, the wall in the blue print is 1 in then the length of the actual wall is 10 feet

A wall in the blueprint is 8 inches, the length of the actual wall is
`10*8= 80` feet

the length of the actual wall= 80 feet
