8 Carson is a decorator. He often sketches his room designs on the coordinate plane. He
has graphed a square table on his grid so that its corners are at the coordinates
,
,
, and
. To graph a second identical table, he reflects ABCD over the yaxis. On the accompanying set of coordinate axes, sketch and label ABCD and its image
A'B'C'D', which show the locations of the two tables. Then find the number of square
units in the area of ABCD.
