Investigate the different shaped bracelets you could make from 18
different spherical beads. How do they compare if you use 24 beads?
How many rectangles can you find in this shape? Which ones are
differently sized and which are 'similar'?
Draw three straight lines to separate these shapes into four groups
- each group must contain one of each shape.
Of course, the perimeter will be measured in units of length, for example, centimetres (cm) while the area will be measured in square units, for example, square centimetres (cm$^2$).
What size square will I need to draw?
What about drawing a rectangle that is twice as long as it is wide which still has a perimeter numerically equal to its area?
