take the cross product of the two vectors and divide it by 2 then u get the area of the parallelogram
if the answer is negative then take it as positive because we take the modulus of cross product , and also the area can never be negative

I tried that way. But it didnot come.
note that it is the diagonals, not sides

Three identical balls are placed on a frictionless
horizontal surface touching each other. They stick to
each other because of adhesive. Another ball of same
radius and mass m is placed over the void created by
the three balls. Find the forces applied by the balls
kept on the floor to each other if the system remains
in equilibrium.
