Students of a school staged a rally for cleanliness campaign in two groups. Group A walked through the lanes AB, BC and CA, while Group B walked through AC, CD and DA. They cleaned the area enclosed within their lanes. If AB = 9m, BC = 40m, CD = 15m, DA = 28m and ∠B = 90°, which group cleaned more area. Also, find the total area cleaned by the students?
