Find perimeter of regular pentagon is 100 inches. find the length of each side.

The length of each side of the polygon is:

                        20 inches.

Regular polygon--

It is a polygon which has all the sides of equal length and all the angles of equal measure.

Also the perimeter of the regular polygon is given as the sum of all the sides of the regular polygon.

i.e. the formula for the perimeter is given by:

where n is the number of sides in a given polygon and s is the length of each sides of the polygon.

Here we have a polygon as a pentagon.

i.e.

and Perimeter=100 inches

i.e.

where are the choices?

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.
