This activity is designed to promote thinking about areas, factors and metric measures. Learners will need to work out the number of tiles, of a given size, that can fit in a rectangular wall or a compound shape made from rectangles. Sections A, B and C ask learners to use square tiles of size, 20cm, 50cm and 25cm respectively. Section D then extends the situation to involve rectangular tiles. Section E then provides two real-life problems to solve.
