Brain Teasers
Paper Room
A room is 12' x 8' when it is designed on paper. You decide to make it square, and take 2 feet off the length and add it to the width to make it 2 feet wider. The room is now 10' x 10'. The total square footage of the first room was 96sq feet, the total footage of the second room is 100sq feet. Where did the extra 4sq feet come from?
Answer
The 2' taken off the first room is 2' x 8' for a total size of 16sq feet. To add it onto the second room you make it 2' x 10', which is 20sq feet. That's the extra 4 sq feet.Hide Answer Show Answer
