Let ABCD be a parallelogram whose diagonals intersect at P and O be the origin, then OA + OB + OC + OD

  • OP

  • 2OP

  • 3OP

  • 4OP


D.

4OP

Since, the diagonals of a parallelogram bisect each other.

Therefore, P is the middle point of AC and BD both.

OA + OC = 2OP  and OB + OD = 2OP OA + OB + OC + OD = 4OP
