Question

Find the perimeter of the given regular polygon.

• A. $60cm$
• B. $90cm$
• C. $45cm$
• D. $120cm$

Answer 1

The correct option is B $90cm$

The sum of all the sides of a polygon is called perimeter. Since all the sides of a regular polygon are equal, the perimeter would be product of number of sides and the length of each side.


Number of sides, $n=6$
Length, $l=15cm$
Hence perimeter, $P=15\times 6$
$\Rightarrow P=90cm$
