The midpoint of line ab is point p at (−16,6). if point a is at (−10,8), what are the coordinates of point b?

If point P is the midpoint of line АВ, then we can write the coordinates of the point P in this form:



We know that   

Now we can write two equations and solve them to find   





B(-22; 4)

You have 2 sides that are 2 cms and you have 6 sides that are 1/2 cm and you have 4 sides that are 1 cm. the smallest sides are 1/2 the medium sized sides are 1 and the smallest are 1/2. so to find the perimeter you have to add them all up together so your answer will be 11 cm's

It would be 18 cm
