Create a rectangle around the parallelogram. the dimensions of this rectangle are . find the area of the four right triangles surrounding the parallelogram. the total area of the triangles is square units. subtract the triangle areas from the area of the rectangle to obtain the area of the parallelogram. the area of parallelogram abcd is square units.

answer: b.

step-by-step explanation:

the y coordinate for point b is 0, and answer b is the only one with that y coordinate.

step-by-step explanation:

given that ab is divided into equal parts as

ac, cd, de, ef, fg, gh, hi, ib.

from this we find that f is the midpoint of ab.

so using mid point formula we find

f = (3,7)

similarly considering fb, we get

h = mid point of fb = ((6,6) and g, mid point of fh is

g = (9/2, 13/2)

i is mid point of hb

so i =(15/2,11/2)
