For the following two block shear failure paths $($red line$)$ in the connection with nine bolts, determine which is the possible failure path $($a or b$),$ and calculate the gross tension area, the gross shear area, the net tension area, and the net shear area for the possible failure path. The standard hole for the bolts. The holes are standard holes and the bolt diameter is $1$ in$.$

$($b$)$
