The activity #4 ((Page 7, Math focus 6)) is as follows:
Ameena made a design by joining hexagons in a row. Each side of a hexagon
is 2 cm. Predict the perimeter of Ameena's design. Explain your prediction.
We have concluded that the perimeter of the design by joining n hexagons
in a row is 8n + 4. How can we check to see if the answer is right?
