(a) Use the information above to construct the hexagon.
(b) Construct a similar figure A1BC1D1E1F1 which has an area of ratio 5:3 to ABCDEF

Observation

This is a question on reduction/enlargement of a given figure. The figure on hexagon Was expected to be drawn from the data provided and by using the knowledge of plane Geometry the hexagon was expected to be enlarged to a similar figure in the ratio 5:3.

Most candidates failed to distinguish enlargement by area from enlargement by side. Some could not draw the hexagon from the data given. However, a good proportion of the candidates did very well in the question. The required solution can be approached from two diifferent ways as shown in the figures marked method 1 and method 2 below:
