Is this is the right answer, i divided 17/20?

17 x 5 = 85. It is the right answer, my way of solving it was different but still correct.

Step-by-step explanation:

4 / 20 = 5

5 x 17 = 85.

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)
