WebThe apothem is the perpendicular line that connects the center of the hexagon with one side. The apothem can be very useful when we want to find the area of a hexagon since it allows us to use a simpler formula. … WebArea of Hexagon Using Apothem. Apothem is the straight line drawn from the center and is perpendicular to the side of the hexagon. Thus, using the apothem, the area of the hexagon is given by: A = 1/2 × Apothem × Perimeter of hexagon. Since the perimeter of the hexagon is equal to the sum of all its sides.
WebArea of Pentagon using Apothem. If the side-length and apothem is given of a pentagon, then; Area of Pentagon = 5/2 x s x a; where ‘s’ is the side of the pentagon, and ‘a’ is the apothem length. Apothem is the line from the center of the pentagon to a side, intersecting the side at 90 degrees right angle. WebTo find the formula for the apothem, we can use the diagram of a pentagon: Here, we divide the pentagon into five congruent triangles and use one of the triangles to find the apothem. We can see that the …
