In parallelogram LMNO, NO = 10.2, and LO = 14.7. The basic property of a parallelogram that the opposite sides in a parallelogram are equal; so, two sides are 10.2 (NO=LM=10.2), and two sizes are 14.7, = (LO=MN=14.7). The perimeter of the parallelogram LMNO is: P= 2NO + 2LO. P= (2 x 10.2)+(2 x 14.7). P= 20.4 + 29.4.
