Answer 1

Answer: The length of the room on blueprint = 10 feet.

Explanation:

Given: On blueprint,

`\frac14` inch = 2 feet

i.e. 1 actual feet =
`2*\frac 14 =\frac12\text{ inch}`

If the actual length of 20 feet, the length of a room on blueprint =
`20*\frac12\text{ feet}`

= 10 feet.

Hence, the length of the room on blueprint = 10 feet.
