Plot the points P(5,5),Q(-3,-3),R(5,-3) . Name the figure obtained on joining the points
P,Q, R . If possible, find the area of the figure obtained


The given figure PQR represents a  right angled triangle, with R=90.Also, using distance formula for two points.QR=-3-52+-3+32=82=8 units.PR=5-52+5+32=82=8 units.Therefore, the area of triangle PQR=12×Base×perpendicular=12×QR×PR=12×8×8=32 square units.
