## What is the formula for area of a regular polygon Quizizz

Find the image(s) that can be used with this area equation: A = 12(b 1 b 2)h There may be more than one right response to the question “What is the formula for the area of a Regular Polygon?”

## What is the formula for a polygon

The measure of interior angles of a regular n-sided polygon is [(n-2)180°]/n. The sum of interior angles of a polygon with “n” sides is 180°(n-2). The number of diagonals in a polygon with “n” sides is [n(n-3)]/2.

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

The basic formula for calculating the area of a regular pentagon is Area of pentagon = 1/2 p a, where p is the pentagons perimeter and a is its apothem.

## What is the formula for perimeter of a regular polygon

Regular polygon perimeter equals (number of sides) x (length of a polygons side) units, or 5 (4) = 20 cm.

## How do you find the area of a regular polygon with the apothem

A = (n s a)2 A = (n s a)2 where n is the number of sides, s is the length of one side, and a is the apothem. You also learned this formula for calculating the area of any regular polygon.

## What is apothem of a polygon

The line segment from a regular polygons center to one of its midpoints, or, more precisely, the line drawn from the polygons center that is perpendicular to one of its sides, is known as the apothem (sometimes abbreviated as apo).

## What is a formula of area of square

The perimeter of a square is equal to four side units, so the area of a square is equal to two side square units.

## What is a formula of area of rectangle

Once the length and width of a rectangle are known, the area can be calculated using the formula: A = l b. By multiplying the length and breadth, the rectangles area is determined to be in square units.

## What is the area of a disk with radius R

A=r2 gives the area of a disk with radius r.

## What is the formula for area and perimeter

**Area and Perimeter Formulas**

Shape | Area | Perimeter |
---|---|---|

Triangle |
A = ½ × b × h |
S = a+b+c |

Square | A = a^{2} |
P = 4a |

Rectangle | A = l × w | P = 2(l + w) |

Parallelogram | A = b × h | P = 2(a+b) |

## What is the formula for area of a polygon

The area of a regular polygon is calculated using the formula Area = (number of sides length of one side apothem)/2, where apothem is calculated as [(length of one side)/2 (tan(180/number of sides))].

## How do you find the area of an irregular shape in 6th grade

Some irregular figures consist of square or rectangular regions; in these cases, the areas of the irregular figures can be calculated by calculating the areas of the squares and rectangles that make up the irregular figure.

## What is the area of a polygon with 4 sides

Use the formula Area = side x side or A = s. For instance, if a squares longest side is 4 feet long (t = 4), its area is simply t 2, or 4 x 4 = 16 square feet.

## What is a polygon 6th grade

If all of a polygons sides are the same length and all of its angles are the same measurement, the polygon is said to be regular.

## How do you find the area and perimeter of a polygon

Start at the top and move clockwise around the shape to find the perimeter. Area of Polygon = (Area of A) (Area of B) To find the area, divide the polygon into two distinct, simpler regions.

## Can a regular octagon have an area of 10

A regular octagon can have an area of 10 units2, but it wouldnt have integral length sides (36 units 18).

## What is next to Hexagon

**List of n-gons by Greek numerical prefixes**

Sides | Names | |
---|---|---|

4 | tetragon | quadrilateral |

5 | pentagon | |

6 | hexagon | |

7 | heptagon |
septagon |

## How do you calculate the area of a polygon

The area of a regular polygon is calculated using the formula Area = (number of sides length of one side apothem)/2, where apothem is calculated as [(length of one side)/2 (tan(180/number of sides))].
