Answer:
49.81
Explanation:
the formula I used is distance=

Lets say we are finding the distance from c to y
c=(-6,9)
y=(5,9)
cy=

cy=

cy=

cy=

cy=11
And you can find the distance between y and i, i and d, d and o, o and c, using the same formula.
After solving the distance of all I got
yi=16.55294536
id=1
do=9.219544457
oc=12.04159458
After you add them all up you get 49.8140844 which rounded to the nearest hundredth is 48.81.
Thank you and I hope that is helpful.
