Question

these three vertices of a rectangle ABCD are A(2,2),b(-3,2)and c (-3,5)Plot these points on a graph paper and find the co-ordinates of D.Also,find the area of a rectangle ABCD.

Answer 1

Step-by-step explanation:

Given, three vertices of rectangle ABCD are A{2,2), B(-3,2) and C(-3, 5).

Now, plotting the points on the graph paper, as shown below, we find that the coordinates of D are (2, 5).

Then, AB = 5 units and BC = 3 units

∴ Area of a rectangle = Length x Breadth

= 3x5 = 15sq units
