Question

study the names of polygons
3 sided
5 sided
8 sided
4 sided
6 sided
10 sided

1. regular polygon - a polygon with all sides congruent.
2. irregular polygon - a polygon that has a different side length.
3. perimeter - a distance around a shape.

** the unit for perimeter is cm, m, km, (single unit because it is len
example find the perimeter of
p=
circumference - is a distance all the way around a circle.
radius - distance from the center to the circle
diameter - distance from one side of the circle to the other p
center

Explanation:

Step1: Recall the formula for perimeter

The perimeter \(P\) of a polygon is the sum of the lengths of its sides.

Step2: Sum the side lengths

Given the side lengths \(AB = 7\) units, \(BC=8\) units, \(CD = 3\) units, and \(DA=5\) units.

$$P=AB + BC+CD + DA$$

$$P=7 + 8+3 + 5$$

$$P=(7 + 8)+(3 + 5)$$

$$P = 15+8$$

$$P=23$$

Answer:

\(23\) units
