The coordinates of the vertices of a polygon are (-2, 1). (-3, 3), (-1, 5), (2, 4), and (2, 1). what is the perimeter of the polygon to the nearest tenth of a unit.

do not label your answer. answer with a number only.

Step-by-step explanation:

step 1

Plot the vertices of the polygon to better understand the problem

we have

using a graphing tool

The polygon is a pentagon (the number of sides is 5)

see the attached figure

The perimeter is equal to

the formula to calculate the distance between two points is equal to

step 2

Find the distance AB

substitute in the formula

step 3

Find the distance BC

substitute in the formula

step 4

Find the distance CD

substitute in the formula

step 5

Find the distance DE

substitute in the formula

step 6

Find the distance AE

substitute in the formula

step 7

Find the perimeter

substitute the values

Round to the nearest tenth of a unit

answer: the answer is one of

step-by-step explanation:   we are given to write a proper fraction where the whole is divided into an even number of equal parts less than ten, and an odd number of those parts exist.

an even number less than 10 may be one of 2, 4, 6 or 8. so, the whole may be one of these four evens.

now, an odd number of these parts must exist, so the numerator must be an odd number, one of 1, 3, 5 or 7. it cannot be 9 because then the fraction will become improper.

thus, our fraction may be one of the following

1. 22

2. 1

3. 7

4. 18
