A regular polygon is equilateral (it has equal sides) and equiangular (it has equal angles).To find the area of a regular polygon, you use an apothem — a segment that joins the polygon’s center to the midpoint of any side and that is perpendicular to that side (segment HM in the following figure is an apothem). Your IP: 158.69.144.84 Here is an equilateral pentagon with all sides of length 2 and two right angles. In order to solve for the perimeter, which is the sum of all sides, we can use a multiplication shortcut of:, where is perimeter, is length of the sides, and is the number of sides of the polygon. The area is referred as the total space occupied inside the Pentagon. In this example, we'll use a pentagon with side length 7 units. the hexagon. The apothem of a pentagon is a line segment from the center of the pentagon to a side of the pentagon. To find the perimeter of an irregular pentagon, you must measure and add up the five sides. The easy calculations are behind us. I built a model using 6 tooth picks, four of which I shortened. You know that: To find the measure of each exterior of a regular polygon, you divide 360° by the number of sides. The area of a cyclic pentagon, whether regular or not, can be expressed as one fourth the square root of one of the roots of a septic equation whose coefficients are functions of the sides of the pentagon.

Pentagon can be sectored into 5 … These lines include the radius and the apothem. an inner pentagon with sides of 10 cm is inside and concentric to the larger pentagon. Start with just the side length. Divide the pentagon into five isosceles triangles, each with a base formed by the pentagon's sides. Finding the Area of a Pentagon. Giving only the lengths of the sides of a polygon with more than three sides is not enough information to find its area. Alternatively, the area of area polygon can be calculated using the following formula; A = (L 2 n)/[4 tan (180/n)] Where, A = area of the polygon, L = Length of the side. User: Find the area of a regular pentagon with side equal to 3 and apothem equal to K. 1.5K 7.5K 12K Weegy: A = (1/2) k (15) A = (15/2) k or A = 7.5 k zaqueo|Points 80| User: Find the area of a regular hexagon with a 48-inch perimeter.48 3 in2 96 3 in2 192 3 in2 Weegy: The area of a regular polygon is given by the formula below.area = ( )(apothem)(perimeter) = 1/2*4 sqrt 3*48 = 96 sqrt3 in2 Draw a pentagon. Take a look at the diagram on the right. while a pentagon's 5 sides can have different lengths (if they all have the same length, it is a regular pentagon). When convex, the pentagon (or any closed polygon in that matter) does have all its interior angles lower than 180°. Let's say we have a pentagon with a side length of 4 cm. $\begingroup$ An irregular polygon can have side lengths being the same, for instance consider an irregular rhombus. The equation is Plug in the numbers for perimeter and number of sides to get Divide each side of the equation by the number of sides to get the answer for the side … Hexagon area formula: how to find the area of a hexagon. An irregular octagon is one which has 8 different sides. Such a polygon can have various shapes, from a square down to a long thin needle of length almost 2. If it is a regular pentagon, just multiply the length of a side by 5.The perimeter of a pentagon is the sum of its sides. Its interior angles are of 108 degrees each and its exterior angles are 72 degrees each. The central five-acre (2.0 ha) pentagonal plaza is nicknamed " ground zero " on the presumption that it would be a prime target in a nuclear war.
