Answer 2

let one of the sides of the parallelogram be 'x' 
Thus, the other side becomes 'x + 25'

Perimeter of the parallelogram = 4x +50 = 150

                                                > 4x + 50 = 150

                                                > 4x = 100

                                                > x = 25

Therefore the 2 adjacent sides of the parallelogram are 25 & 50
