Answer:
Step-by-step explanation:
Alright, lets get started.
For finding the perimeter, lets first find all sides
Side between point (5,8) and (12,0) is :
[tex]\sqrt{(12-5)^2+(0-8)^2}[/tex]
[tex]\sqrt{49+64}[/tex]
10.63
side between point (12,0) and (-5,0) is :
[tex]\sqrt{(-5-12)^2+0} = 17[/tex]
Side between point (-5,0) and (-12,8) is :
[tex]\sqrt{(-12+5)^2+(8-0)^2} = 10.63[/tex]
Side between (-12,8) and (5,8) is :
[tex]\sqrt{(-12-5)^2+(8-8)^2}=17[/tex]
So, the perimeter will be addition of all 4 sides
Hence perimeter is = [tex]10.63+17+10.63+17 = 55.26[/tex]
So rounding off to nearest tenth,
the perimeter is 55.3 unit : so the answer is B
Hope it will help :)
