Question

Topic 2. Coordinate Geometry
(hint: 1. Plot the points (-2,5), (3,0) and (-2,-4) on a graph paper
2. Join the coordinates. Which figure is formed ?
3. Find the area and the perimeter of figure so formed ?)​

Answer 1

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.
