Question

Dinnerware Design: You are designing dinnerware. What is the length of a side of the smallest square plate on which a 20cm chopstick can fit along a diagonal without any overhang? Round your answer to the nearest tenth of a centimeter.

Answer 1

The diagonal of a square serves as the hypotenuse to a right-angle triangle, for which the other two sides are equal. Thus:

20² = x² + x²
x = √200
x = 14.1 cm
