M3.1

Rosette Weaver

Size the polygon so ONE full lap around it measures exactly the target — then type how many metres that lap is (careful: your sides are in centimetres!) and press Check.

🎯 One lap = the target length. Sides are in cm, the target is in metres — so you'll need to ÷100.

The perimeter is the distance once around the edge: sides × side length. The pen counts up the centimetres as it walks. The target is in metres — remember 100 cm = 1 m, so divide by 100.
