Question

Find the side of a regular octagon with perimeter 42 cm

Answer 1

Answer:

42/8 = 5 1/4 cm is the answer

Answer 2

Answer:

The side of regular octagon is 5.25 cm

Step-by-step explanation:

In a regular octagon all the sides are equal

Perimeter of regular octagon = 8 × S

Perimeter of regular octagon = 42

8 S = 42

S = 42/8

S = 5.25

Therefore, the side of regular octagon is 5.25 cm

Check ⇒

Perimeter of regular octagon = 8 × S

S = 5.25 cm

Perimeter of regular octagon = 8 × 5.25

                                                 = 42 cm

Hence, it is the correct answer.
