To determine how I'golden" a rectangle is, you simply divide the length by the width, and see if the result is close to the golden ratio (about 1.618). Keep in mind that in geometry, length refers to the longer side and width refers to the shorter side. I recommend using the cm side of the measuring tape if you can, since cm are measured in tenths and are easier to work as with as decimals rather than inches which are broken down into 16ths and require use of fractions. You can copy this activity to your own paper or print this one and use it. Measure the given objects accurately and include units in your measurement (such as inches or cm). When calculating the ratio for each rectangle, round accurately to 3 decimal places. See the example in Canvas to make sure you don't lose points for not following the instructions. For the bottom three rows of the table, choose rectangular objects that you think might be \"golden\" and measure them. Enter the description in the rst cell for each row.
