How To Find The Area Of A Regular Polygon?

How do u find the area of a regular 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.

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 regular polygon with the radius?

Find area of regular polygon given radius –

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 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.

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.

How fo you find the area of a triangle?

Example finding area of triangle –

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.

Is the Apothem equal to the side?

The apothem refers to the length of the line the connects the center of a regular polygon to the midpoint of any of the sides. A regular polygon has all congruent sides; if the polygon is irregular, there is not a midpoint equidistant from the midpoint of all sides. You can calculate the apothem if you know the area.
