Plot the points A(2,2) B(6,2), C(8,5) and D(4,5) in a graph sheet. Join all the points to make it is a parallalogram. Find its area.

Plot the points (0,0), (0,3), (4,3), (4,0) in graph sheet. Join the points with straight lines to make a rectangle. Find the area of the rectangle.

Plot the points (2,3), (6,3) and (4,7) in a graphsheet. Join them to make it a triangle. Find the area of the triangle.

Let's plot the points A (4,0), B(0,6), C (2,5), D(7,1) E (?, 5) and F(?,5) on a graph sheet.

Show that the points (-4, -7), (-1, 2), (8, 5) and (5, -4) taken in order are the vertices of a rhombus. Find its area. (Hint : Area of rhombus = (1)/(2)xx product of its diagonals)

Prove that the points A (-2,-1) , B (5,4) C (6,7) and D (-1,2) are the vertices of a parallelogram.

Prove that the points (2,-2) ,(8,4), (5,7) and (-1,1) are the vertices of a rectangle , find the area of the rectangle.

Show that the four points (2,5),(5,9), (9,12) and (6,8) when joined in order , form a rhombus .
