If the side lengths of a polygon are: 4x, 6x, 12, and 18 what is the value of x if the perimeter is 118?
Sonja [21]

The value of x for given polynomial is 8.8.

<h3>What is Polygon?</h3>

The definition of a polygon is given as a closed two-dimensional figure with three or more straight lines.

Here, the length of sides of given Polygon are:

    4x, 6x, 12, 18

Perimeter of polygon = 118 units.

We know that,

Perimeter of polygon = Sum of all sides

                             118 = 4x + 6x + 12 + 18

                             118 = 10x + 30

                             118 - 30 = 10x

                               10x = 88

                               x = 88/10

                               x = 8.8

Thus, the value of x for given polygon is 8.8.
