Question 9 (a) The length of a hallway in an office is 8.4 metres. On a scale drawing of the office, the hallway has a length of 70 mm. Determine the scale used to make the drawing. Give your answer in the form 1:n, where n is a whole number. (b) A plan for an area outside the office is drawn to a scale of 1:200, and on this plan, a rectangular courtyard is 4.8 cm wide and 11.4 cm long. If this courtyard is paved with square pavers measuring 30 x 30 cm, determine how many pavers it contains.
