Question

A blueprint for a house has a scale of 1:35. A wall in the blueprint is 3 in. What is the length of the actual wall?

Answer 1

See explanation.

Explanation:

The scale `1:35` means that real wall sizes are `35` times bigger than on the blueprint.

So if the blueprint is `3` inches long, the wall is

`3xx35=105` inches long.

Answer:

The wall is `105` inches (`8'` `9''`) long.
