There is a trapezoid. If the upper bottom is increased by 2 meters, the lower bottom and height will not change. Its area will increase by 4.8 square meters. If the upper bottom and the lower bottom are both unchanged, and the height is increased by 2 meters, its area will increase by 8.5 square meters. Find the area of the original trapezoid

Height of trapezoid: 2 × 4.8 △ 2 = 4.8 (m) sum of top and bottom of trapezoid: 2 × 8.5 △ 2 = 8.5 (m) area of original trapezoid: 4.8 × 8.5 △ 2 = 20.4 (M2) answer: area of original trapezoid is 20.4 square meters
