Answer:
The figure obtained by joining the points (-3,0), (0,-2), (3,0) and (0,2) [in order] is in fact:
Given points are (0,2),(3,0),(0,−2) and (−3,0).
The points are plotted in the graph below.
The quadrilateral obtained is a rhombus.
BD and AC are the diagonals of the rhombus.
Area of a rhombus =1/2×d1×d2
Where d1 and d2 are the length of diagonals.
AC=4 units [from graph]
BD=6 units [from graph]
Area of rhombus ABCD=1/2×BD×AC
=1/2×6×4
=12sq.units.
Hence the area is 12sq.units.
