Plz i need this an expression for the perimeter of the triangle shown below: a triangle is shown with side lengths labeled 2.3x plus 14, 2x, and negative 0.2x plus 15.

a: 4.1x + 29
b: 4.1x - 29
c: 4.5x+ 29
d: 4.5x -29

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)
