using tape. Find the length of the tape required.​

Answer 1

Answer:

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 )
