Question

what are the perimeter formulas for regular shapes

Answer 1

Step-by-step explanation:

A polygon that has all its sides equal with equal angles. The sum of the angles of a polygon with n sides, where n is 3 or more, is 180° × (n - 2) degrees. ...

Since the area is given we now have: ...

Divide each side by 3. ...

We know that the perimeter of the regular polygon is given by: P = ns.

hope it help you

thank you
