Question

Three vertices of a rectangle are A(1,3),B(1,-1) and C(7,-1).Plot these points on the graph paper and

hence use it to find the coordinates of the fourth vertex.Also find the area of the rectangle.​

Answer 1

Step-by-step explanation:

From the graph,

The coordinates of point D are (3,3).

Area of rectangle ABCD=l×b=AB×BC

On further calculation we get

Area of rectangle ABCD=6×2

Area of rectangle ABCD=12 sq. units
