Step-by-step explanation:

Answer

Given three vertices of a rectangle are A(2,−1),B(2,7)andC(4,7).

These points are marked on the graph shown below.

Join the points to form rectangle ABCD.

Also join the diagonals AC and BD

The coordinates of fourth vertex D is (4,−1)

(ii) The midpoint of CD is (4,3).

By using distance formula

AB=

(x 2 −x ! ) 2 +(y

2 −y!)

2 =

(2−2) 2 +(7−(−1)) 2 = 8 2

=8BC= (4−2) 2 +(7−7) 2

= 2 2

=2

Area of rectangle=AB×BC

=8×2

=16sq.units
