2. Complete Activity 7.2 (Page 81). Use the data given in Activity 7.1 to draw a graph. Take age on the X-axis and per cent growth in height on the Y-axis. Highlight the point representing your age on the graph. Find out the percentage of height you have already reached. Calculate the height you might eventually reach. Tally your graph with the one given here (Fig. 7.1).
Answer: The graph is drawn below:
Right now my age is 12. Therefore, from the graph I get that percentage of height you have already reached = 84%.
My current height is 140 cm.
Therefore, the height I might eventually reach = 140/84 × 100 = 166.7 cm. The graph is very similar to the one given in the question.
