The diagram shows a scale model of a garage. Its width is 7 cm, its length 12 cm and the height of its walls 8 cm. a) If the width of the real garage is 4m, calculate: (i) The length of the real garage (ii) The real height of the garage wall. b) If the apex of the roof of the real garage is 2m above the top of the walls, use Pythagoras' theorem to find the real slant length I. c) What is the area of the roof section A on the model?
