Detailed Solution

Given, each side of a polygon is 3.8 cm in length and its perimeter is 22.8 cm.
We can find the number of sides as,

Number of sides of the polygon = \frac{Perimeter of the polygon}{length of each side}

= \frac{22.8}{3.8}

= 6
Hence, the total number of sides is 6.
So option 1 is correct.
