Deprecated in 2016 for quality reasons.  Replaced with article: https://www.khanacademy.org/cc-early-math-measuring-length/a/measuring-lengths-with-different-units.

### Problem

This is a rectangle.
Let's measure the start color green, g, r, e, e, n, space, l, i, n, e, end color green below using both rectangles and a centimeter ruler:
