How do you find area of a polygon?

How do you find area of a polygon?

To find the area of a regular polygon, all you have to do is follow this simple formula: area = 1/2 x perimeter x apothem. Here is what it means: Perimeter = the sum of the lengths of all the sides….Plug the apothem and the perimeter into the formula.

1. area = 1/2 x 120 x 10√3.
2. area = 60 x 10√3.
3. area = 600√3.

What is an area of polygon called?

Area = n∗s∗a/2. Where n is the number of sides, s is the length of a side, and a is called apothem. The apothem is the length of a perpendicular line that connects the center of the polygon to any of its sides. Area of n-sided polygon.

What are polygon regions?

A polygonal region is defined as a polygon and its interior. The perimeter of a polygon is the distance around the figure. The area of a polygonal region is measured in square units. For every polygonal region, there is a unique positive number called the area of the region.

What is apothem in polygon?

The apothem (sometimes abbreviated as apo) of a regular polygon is a line segment from the center to the midpoint of one of its sides. Equivalently, it is the line drawn from the center of the polygon that is perpendicular to one of its sides.

What do you mean by polygon?

A polygon is a two-dimensional geometric figure that has a finite number of sides. The sides of a polygon are made of straight line segments connected to each other end to end. Thus, the line segments of a polygon are called sides or edges.

How many polygons are there?

A Polygon is classified based on its sides like a triangle, quadrilateral, pentagon, hexagon, heptagon, octagon, nonagon, and decagon according as it contains (3, 4, 5, 6, 7, 8, 9) and (10) sides, respectively….Types of Polygons with Sides 3-20.
