You have a piece of paper, 10cm by 10cm. Area = 100cm^2. For some reason, you need a square piece of paper with an area of 50cm^2. Using the paper you have, what's an easy way of getting the new square?

Open Calculator


Answer

Fold the four corners of the square into the centre. This doubles the thickness of the paper, and so halves the area.
