Answer:
[tex]42\:\mathrm{cm}[/tex]
Step-by-step explanation:
The perimeter of a polygon is equal to the sum of all the sides of the polygon. The polygon in the figure is a hexagon (polygon with six sides) and it is implied that all sides are equal. If each of the sides are 7 cm long, the perimeter must be [tex]7+7+7+7+7+7=7\cdot 6=\boxed{42\:\mathrm{cm}}[/tex].
*It's good to note that the units for perimeter is the same unit as the sides are given as, because we're only adding the sides of the polygon.
