Age 14 to 16
Challenge Level
Using only compasses and a straight edge, construct this design so that each "tear" is $100 \; \text{cm}^2$.
So that your diagram is the right size you will need to calculate one length, to get you started.
Do this as a single calculation, then take that result as the initial setting for your compasses.
You can then create the design without further calculation or use of a ruler
(a protractor is not necessary for any part of the process).
