The following figures are examples of polygons : Regular polygon A regular polygon is a polygon … However, if i replace the area attribute with 'perimeter' I get the following message: 'Polygon' object has no attribute 'perimeter' which seems absurd. Also consider that the two opposite sides of the polygon are equal. If we are looking to find the perimeter of basic polygons such as triangle, rectangle, parallelogram, rhombus, trapezoid, kite, pentagon, and hexagon, we can also use their standard formulas that are given below: For determining the area of a polygon given on a coordinate plane, we will use the distance formula to determine the lengths of all its sides, adding the lengths will give the perimeter of the polygon. Multiply the side length by the number of sides to get the perimeter. The coordinate values displayed are those used to calculate the area and perimeter, so changing the displayed decimal digits may change the x and y coordinate values and may result in the calculation of different values for the polygon's area and perimeter. A polygon is a 2-dimensional figure, but the perimeter is a one-dimensional measurement. So x = 12 cm. For example, if you’re working with a rectangle that has 2 sides that are 4 units long and 2 sides that are 3 units long, you would write “4, 4, 3, 3.”, If you’re working with an irregular polygon that has 1 side that’s 2 units, 1 side that’s 3 units, and 1 side that’s 4 units, you would write “2, 3, 4.”.
