Consider the system shown below where four point masses are connected to each other by massless rods. Two of the masses are $m=9kg$ and the other two have the masses of $M=4kg.$ If $a=1,8m,b=1,7m$ and the system rotates about $y-$axis, determine the moment of inertia of the system. Express your answer in units of $kg*m^2$ using one decimal place.
