Step-by-step explanation:
Plot the points (2, 3), (-2, 3), (-2, -3) and (2, -3) on a graph sheet. Join these points. Name the figure obtained. Also, find the area of the figure so obtained.
The figure obtained is a rectangle.Area of the rectangle = 4 × 6 = 2
The figure obtained is a rectangle.
Area of the rectangle = 4 × 6 = 24 square units
Example 8. Mark the points (2, 2), (2, -2), (-2, -2) and (-2, 2) on a graph paper and join these points. Name the figure that you obtain. Also, find the area of the figure so obtained.
