you clicked the right answer hehe. the opposite or facing sides of a parallelogram are of equal length and the opposite angles of a parallelogram are of equal measure.
OP is of equal length to MP which means OP is also 21m and that makes x equals to 11.
to find y, we have to make sure that the result of LP and NP are of equal length. Therefore, y is equals to 2 because;
LP = (y+3)m = (2+3)m = 5m
NP = (3y-1)m = (3(2)-1)m = (6-1)m = 5m
LP=NP. the answer is letter D. x=11 and y=2
