Area & Perimeter

Tile it, walk around it

Perimeter is the length all the way round a shape; area is how much surface it covers. In this chapter you will put lace round a quilt, cover shapes with square tiles, and find the biggest rectangle a length of lace can go round.

Think about it

Two rectangles both need 24 units of lace round the edge. Do they have the same area?
