Answer:
The choose a. – 2
Step-by-step explanation:
Point slope form is
y-y1=m(x-x1)
where slope=m
and (x1,y1) is a given point
slope=(y2-y1)/(x2-x1)
slope=(6-7)/(-8-(-5))=-1/(-8+5)=-1/-3=1/3
pick any point
(x,y)
(-5,7)
y-7=1/3(x+5) or
y-6=1/3(x+8)
If it's width is 10cm then it's legth has to be 40cm. So 10+10+40+40=100cm Perimeter
