# Kajal wants to seal a box in the shape of a regular octagon of side 15cm using tape. Find the length of the tape required

As given  : Kajal wants to seal a box in the shape of a regular octagon of side 15 cm using tape .

From that we get Length of each side of regular octagon  =  15 cm
And
Length of tape required to seal the regular octagon shaped box  =  Perimeter of regular octagon
And

We know Perimeter of regular octagon  =   8 ( Side of regular octagon ) , So

Perimeter of our regular octagon shaped box  =  8 $×$ 15  =  120 cm
So,
Length of tape required to seal the regular octagon shaped box  =  120 cm                             ( Ans )
