How To Find The Area Of A Polygon?

How do you find the area of a regular polygon?

Find the Area of Regular Polygons –

What is the formula for finding the area of a pentagon?

Using a Formula. Area of a regular pentagon = pa/2, where p = the perimeter and a = the apothem. If you don’t know the perimeter, calculate it from the side length: p = 5s, where s is the side length.

How do you find the area of a polygon with vertices?

Determinants to Find the Area of a Polygon –

What is the area of quadrilateral?

To find the area of a rectangle, you need two measurements: the width, or base (the longer side of the rectangle), and the length, or height (the shorter side of the rectangle). Then, just multiply them together to get the area. In other words: Area = base × height, or A = b × h for short.

What is the area of this trapezoid?

Explanation: To find the area of a trapezoid, multiply the sum of the bases (the parallel sides) by the height (the perpendicular distance between the bases), and then divide by 2.

What is the 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. Apothem = a segment that joins the polygon’s center to the midpoint of any side that is perpendicular to that side.

How do you find the area of Apothem?

To find the area of regular polygons, use the formula: area = (ap)/2, where a is the apothem and p is the perimeter. To find the apothem, divide the length of one side by 2 times the tangent of 180 degrees divided by the number of sides.

How do you find area?

To find the area of a rectangle multiply its height by its width. For a square you only need to find the length of one of the sides (as each side is the same length) and then multiply this by itself to find the area. This is the same as saying length2 or length squared.

What are the names of irregular shapes?
