Answer:
D(3,2)
Step-by-step explanation:
First apply distance formula as AB = DC and BC = AD
From this you will get a equation
x + 3y = 9
And after this apply area formula
to find the area of triangle ABC and ADC areas of both the triangles will be same as the bisector of a parallelogram divides it into 2 congruent triangles
From this you will get a equation
3x - y = 7
By solving both the equations you will get
x = 3
y = 2
