Maryam showed the location of each vertex of a polygon on the grid below.

If the points are connected, which statements about the polygon are true? Check all that apply.

The polygon has six sides.

The polygon is a pentagon.

The vertices of the polygon are (–2, 1), (1, 3), (4, 1), (3, –3), and (–1, –3).

The polygon has five vertices.

The polygon is a heptagon.

part 1 answer = 8

part 2 answer = 72

step-by-step explanation:

part 1 explanation = add all of the numbers, then divide by how many numbers you have. so, 200/25 = 8.

part 2 explanation = not gonna lie, this is hard to explain, so just google how to do it.

468

step-by-step explanation:

perimeter = 10 +  √10  units

explanation:

first, we will need to get the length of each line using the distance formula which is as follows:

distance = 

1- length of ab:

ab =   = 5 units

2- length of ac

length of ac is the same as ab = 5 units

3- length of bc:

bc =   =  √10  units

now, we can get the perimeter by adding the side lengths as follows:

perimeter = 5 + 5 +  √10

perimeter = 10 +  √10  units

hope this : )
