Area of polygon formula

Area Formulas. This formulas help you answer the questions how to find the area of triangle, square, rectangle, rhombus, parallelogram, trapezium, quadrangle, circle and ellipse.

So we're going to say the area of any regular polygon is equal to apothem times side length times the number of sides divided by 2, or if we substitute in for n times s, it's going to be the apothem times the perimeter divide by 2. So you have 2 different formulas, both of which will calculate the area of any regular polygon.

There’s a very simple algorithm when you’re given the coordinates of the vertices. I worked it out here: What is the meaning in mathematics of negative area? I don’t like answers that are just links, so let’s fill this out a bit.

Area of polygon formula

STANDARD G.MG.A.3 GEO. Apply geometric methods to solve design problems (e.g., designing an object or structure to satisfy physical constraints or minimize cost; working with typographic grid systems based on ratios).

NOTE: The area of a polygon that has infinite sides is the same as the area a circle. Depending on the information that are given, different formulas can be used to determine the area of a polygon, below is a list of these formulas: The length of a side is given: By definition, all sides of a regular polygon are equal in length. The last expression is known as Heron's formula. A polygon, area of which we want to determine, can be divided into some triangles by its diagonals. A polygon, circumscribed around a circle ( Fig. 67 ), can be divided by lines, going from a center of a circle to its vertices. Then we receive:
