#### 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 coordinates of the fourth vertex D Also find the co-ordinates of

(i) the mid-point of BC

(ii) the midpoint of CD

(iii) the point of intersection of the diagonals. What is the area of the rectangle?
