Measuring Pastures: Warmup Problem

1.  On the Cut-out Shapes pages, you will see 11 half-circles.  Cut out all 11.  Use all of the  half-circles to make three figures.  Each piece may be used only once.  Two of the three figures you make will have this shape (not necessarily the same size):

[[{"fid":"327","view_mode":"default","type":"media","attributes":{"height":217,"width":280,"class":"media-element file-default"}}]]

and one will have this shape:

[[{"fid":"328","view_mode":"default","type":"media","attributes":{"height":227,"width":333,"class":"media-element file-default"}}]]

2.  Compare your three figures.  Predict which one has the greatest length around the outside.  (You may know the word ‘perimeter’ for this length.)  Once you have made your prediction, find a method to determine if you are correct.   (Measuring the lengths is permitted.)
