Question

Each side of a regular polygon is 2.5cm in length. The perimeter of the polygon is 12.5cm . how many side does the polygon have?

Answer 1

Answer:

5 sides

Step-by-step explanation:

Let the number of sides be x

Since the given polygon is regular .

So, all the sides of the polygon are equal

Perimeter of regular polygon = $\text{no. of sides} \times \text{Side length}$

                                                = $x\times \2.5$

Since we are given that  The perimeter of the polygon is 12.5cm .

So,  $12.5=x\times 2.5$

$\frac{12.5}{2.5}=x$

$5=x$

Thus the given polygon has 5 sides
