The formula for the area, a, of a regular polygon in terms of the perimeter of the polygon, p, and the length of the apothem, a,

kotykmax [81]

The equivalent equation that can express the area of a polygon in terms of the perimeter is given by A = P/2

<h3>What is Polygon: </h3>

A closed, two-dimensional object composed of straight lines is called a polygon. Typically names of polygons are based on the polygon's number of sides Like triangles, rectangles, pentagons, etc.

<h3>Apothem of a polygon: </h3>

a line segment connecting the midpoint of a side to the center of a regular polygon is known as the Apothem of a polygon.

The area of a polygon with Apothem is given by

<h3> Area = 1/2 × perimeter × apothem </h3>

Here given that

Number of sides of Polygon = 5 sides

Let P be the perimeter

Given the length of the Apothem = a

By the given formula,

Area of the Polygon, A = (1/2) [P][a]

=> A = P/2

Therefore,

The equivalent equation that can express the area of a polygon in terms of the perimeter is given by A = P/2

The circumference of Fis 120 cm. What is the length of DË (the minor<br> arc)?

Afina-wow [57]

Answer:

15cm

Step-by-step explanation:

Let x be the arc circumference.

The circumference of a circle usually subtends to 360°, that is, one complete revolution is 360°.

#Given the arc angle as 45° and the circumference as 120cm, the arc circumference can be obtained as:

#Apply proportions to find x:

$360\textdegree=120cm\\45\textdegree=x\\\\x=(120/360)\times 45\\\\x=15cm$

Hence, the arc circumference is 15cm
