Question

Q30. Locate the points A(3, 2), B(-3,2), C( 3,-2) and D(-3,-2). Join the points and name the figure so obtained and find its area..

Answer 1

Let X

′

OX an dY

′

OY be the coordinate axes. Then, the four points may be plotted as given below :

Let X’ OX and Y’ OY be the coordinate axes and mark point on it.

Here, point P(-3,2) lies in II quadrant, Q(-7,-3) lies in III quadrant, R(6, -3) lies in IV quadrant and S(2,2) lies in I quadrant. Plotting the points on the graph paper, the figure obtained is trapezium PQRS.
