​​Calculate 6706

Given a triangle KLM points K [-3.2] L [7, -3] M [8.5]. ​​Calculate the side lengths and perimeter.

Correct answer:

k =  8.0623
l =  11.4018
m =  11.1803
o =  30.6444

Step-by-step explanation:

x0=3 y0=2  x1=7 y1=3  x2=8 y2=5  k=(x1x2)2+(y1y2)2=(78)2+((3)5)2=65=8.0623
m=(x0x1)2+(y0y1)2=((3)7)2+(2(3))2=5 5=11.1803
