- 1 The distance all the way around Perimeter is the distance around a shape's edge. Add it up in length units, like centimetres or metres. · 4 min
- 2 The rectangle shortcut A rectangle has two side lengths, called length and breadth. Its perimeter is twice their sum. · 5 min
- 3 How much space is covered Area is how much flat space a shape covers. Counted in whole unit squares, like square centimetres. · 4 min
- 4 Tiling a rectangle The area of a rectangle is its length times its breadth. Counting the tiled unit squares proves it. · 5 min
- 5 Same rope, different land A fixed perimeter does not fix the area. The same rope length can fence very different amounts of space. · 5 min
- 6 Measuring the real world Real objects need the right unit. Real rooms are not always plain rectangles. · 5 min
- 7 The big picture Six ideas, tied together, and a look at what comes next. · 3 min
