Question

. The three vertices of a parallelogram ABCD are A(-2,2), B(6,2)and C(4 ,-3), Plot these points on a graph paper and hence use it to find the co ordinates of the fourth vertex D. Also write the coordinate of midpoint of CD. What is the area of ABCD?

Answer 1

Answer:

D = (-4,-3)

midpoint of CD = (-3,0)

area = 8×5 sq. units = 40 sq. units .
