Question

what is the perimeter of a regular decagon with side 17 cm long​

Answer 1

Perimeter of regular decagon (P) = 170cm

Step-by-step explanation:

Regular Decagon

The 10 sided polygon having the measure of 1440° interior angle is called as regular decagon

___________________________

Perimeter of regular decagon (P) =10a

Here a = side

Perimeter of regular decagon (P) =10a

Perimeter of regular decagon (P) =10 × 17

Perimeter of regular decagon (P) = 170cm

Perimeter of regular decagon (P) = 170cm

Answer 2

Answer:

The parameter of a decagon of side 17cm​ is 170 cm.

Step-by-step explanation:

• Perimeter is the distance around the edge of a shape.
• Means Perimeter is an addition of all sides.
• A decagon is a ten-sided polygon.

So, perimeter of decagon = 10 (side)

If side = 17cm

Then perimeter of decagon = 10 (side)

= 10 (17)

= 170 cm

So, the perimeter of decagon is 170 cm.
