The correct answer to the above question is option A.

24 To calculate the area of triangle QRS, in the vertices of parallelogram in the image above, we need to determine the base and height of triangle QRS. The base QR = 6 (from -3 to 3) The height RS = 8 (from -5 to 3) Area of a triangle = ½ base height Therefore the area of triangle QRS = ½ 68 = 24 The area of QRS is 24 square units Hope this helps.
