Question

Find the value of $m\times n$ if :

$m:$ Number of lines of symmetry of regular hexagon

$n:$ Number of lines of symmetry of regular heptagon

• A. 42
• B. 1
• C. $484$
• D. $468$

Answer 1

The correct option is A 42

Number of lines of symmetry in a regular polygon is equal to number of sides of the polygon.

So, number of lines of symmetry of regular hexagon $\left(m\right)$ = 6

and number of lines of symmetry of regular heptagon $\left(n\right)$ = 7


$\therefore m\times n=6\times 7=42$
