Answer 2

Answer:

Pentagon, with 5 sides.

Step-by-step explanation:

Length of each side of the polygon = 2.5 cms.

Perimeter of the polygon = 12.5 cms.

Perimeter = length of each side * number of sides.

Hence, $12.5=2.5n$, where n is the number of sides.

Therefore, $n=\frac{12.5}{2.5}$

That is, $n=5$

Hence, the polygon is a pentagon, with 5 sides.

Hope it helps.
