Three vertices of a rectangle are A(2, -1), B(2, 7) and C(4, 7). Plot these points on a graph and hence use it to find the co-ordinates of the fourth vertex D. Also find the co-ordinates of
(i) the mid-point of BC
(ii) the mid-point of CD
(iii) the point of intersection of the diagonals.
What is the area of the rectangle ?
