An isosceles trapezoid has a perimeter of 60.1 miles. Its shorter base measures 13.1 miles and its longer base measures 20 miles. The two remaining sides have the same length; what is that length?​

astronomers is your final answer! : )

correct answer is b. 27/8

step-by-step explanation:

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)
