The coordinates of the vertices of the triangle are (–8, 8), (–8, –4), and . Consider QR the base of the triangle. The measure of the base is b = 18 units, and the measure of the height is h = units. The area of triangle PQR is square units.

Answer:The height of the triangle PQR is given by:h = 4 + 8h = 12 unitsNow, the area of the triangle PQR is:= 108 square units.Step-by-step explanation:
