Answer 1

Answer:

6x+13y

Step-by-step explanation:

PERIMETER OF QUADRILATERAL = SUM OF ALL SIDES

                                                         = (2x-3y)+(7x+y)+(x+12y)+(3y-4x) units

                                                        = (2x-3y+7x+y+x+12y+3y-4x) units

                                                        = (6x+13y)
