CSEC Mathematics · January 2004 · Paper 2 · Question 8(c)

A table shows how the number of unit lengths in each side of a figure is related to the number of basic triangles in that figure. The table has rows for 'Number of unit lengths in each side of figure' (1, 2, 8) and 'Number of basic triangles in that figure' (1, 4, 9).

The table below shows how the number of unit lengths in each side of a figure is related to the number of basic triangles in that figure. Copy and complete the table.

The mark scheme is shown once you've answered.
