I took the test and got it correct.

Answer 2

Answer:

32.1

Step-by-step explanation:

d=sqrt ((x2-x1)^2+(y2-y1)^2 )

Find length of AB

d=sqrt((2-(-4))^2+(0-5)^2)

d=sqrt(6^2+(-5)^2)

d=sqrt(36+25)

d=sqrt(61)

d= around 7.8

Find length of BC

d=sqrt((4-(-4))^2+(10-5)^2)

d=sqrt(8^2+5^2)

d=sqrt(64+25)

d=sqrt(89)

d= around 9.4

Find length CD

d=sqrt((8-4)^2+(7-10)^2)

d=sqrt(4^2+(-3)^2)

d=sqrt(16+9)

d=sqrt(25)

d=5

Find length DE

d=sqrt((4-8)^2+(5-7)^2)

d=sqrt((-4)^2+(-2)^2)

d=sqrt(16+4)

d=sqrt(20)

d= around 4.5

Find length EA

d=sqrt ((4-2)^2+(5-0)^2 )

d=sqrt(2^2+5^2)

d=sqrt(4+25)

d=sqrt(29)

d= around 5.4

P=7.8+9.4+5+4.5+5.4

P=32.1
