Question

The perimeter of a regular decagon is 70 m. How long is each side? 5 m 6 m 7 m 10 m

Answer 1

Option C

ANSWER:

The length of each side of the regular decagon is 7 m.

SOLUTION:

Given that, a regular decagon has perimeter equal to 70 meters.

We need to find the length of each side.

Let the length of each side be "d"

We know that a regular decagon will have ten sides.

Each side is of equal length.

So, perimeter of decagon = d + d + d + d + d + d + d + d + d + d

$70 = 10 \times d$

$\frac{70}{10} = d$

d = 7 m

Hence, the length of each side of the regular decagon with perimeter 70 m is 7 m.

Answer 2

Answer:

7

Step-by-step explanation:

Because decagon has 10 sides. If the perimeter is 70, I would divide it. 70/10 = 7

Pardon me if I turn out to be wrong, but that is how I think you would solve this.
