# Triangle and parallelogram in the space

Area of triangle formed by \(\overline{a_1}=(3,1,2), \overline {b_1} = (3,-5,5)\) is equal to the area of the parallelogram formed by \(\overline{a_2} = (4,7,3), \overline{b_2}=(4,6,x)\). Let \(y_1\) and \(y_2\) are the possible values that satisfy \(x\). What is the value of \(\lfloor y_1+y_2 \rfloor\)?
